The word 'curated' from Microsoft makes it sound like it will be select titles that will developed specifically for the hardware though. My guess is 1st party and other select big 3rd party games that they would want to have run well. Otherwise it will be PC version available.
I mean in theory this could be a very nice "do everything" device...
Curated is about the experience, not the games. MS would have to update developer documentation 12-18 months before hardware release.
As things stand now, the documentations requires the use of GDKX for Xbox Console SKUs.
Instruction on using the Game Development Kit (GDK)

It's simple:
GDK creates Xbox PC scalable SKUs that are run on PCs, Laptops, and Handhelds.
GDKX takes most of that code and creates a new SKU for Consoles that also are used on xCloud.
Play Anywhere licensing ties the both SKUs together.
Biggest variation between the GDKX version is how it makes use of the unified memory structure aka the GDDR7 vram.
In a perfect world, MS would prefer a fully unified ecosystem under one license. They want BOTH scalable PC versions and fixed spec optimized versions. All under one license. However, certain major publishers with their own PC storefronts prevent a fully unified ecosystem, primarily EA, Ubisoft, Rockstar. So MS would prioritize a fixed spec optimized version mainly due to two reasons. For xCloud, and the fact that PC games can break with any variant hardware in the future and dev or publisher may not be around to fix it.
When Nadella said, the Xbox Console was created to build a better PC, people made fun of him and misunderstood him. What he was referring to is the fact that Consoles get Fixed Spec Optimized code that can last for decades.
What MS is trying to do is create a baseline for the fixed spec hardware to be used for ALL three major PC ecosystems, Epic, Steam, Xbox. So devs from other stores can use the same hardware for optimizing their games toward. So it's not just about bringing PC games to consoles but bringing fixed spec optimizations to PC.
That's why I believe both Xbox PCs and Xbox Consoles running on Magnus will be able to run those GDKX versions.
You are right that the Optimizations are mainly required for AAA games. For indies, it could run the exact same GDK code. MS could have devs do what they do for the handhelds, use the GDK SKU and have presets for the fixed spec hardware, which is also what Epic and Steam versions via Windows SDK would be doing.
But that is optional, the Consoles are required to use the GDKX for guaranteed Optimized versions, otherwise that game wouldn't be certified to be published on Consoles xbox store.
My point is that MS is neither getting rid of GDKX SKUs, and neither getting rid of Play Anywhere. If they were, the documentation would change, next big GDK update is in April.
You can't really lock the console down if it has multiple PC storefronts. Maybe outside not being able to install other operating systems like Linux.
Jez (near 100% track record on Windows Central rumors) states that you can run Photoshop on the new Xbox. That tells me all I need to know about how this will work.
Sure you can lock down full windows, there is precedent with Windows 11 Home S mode or Windows 10X.
MS could do what Google is doing with Epic settlement for Android, allow registered and approved third party stores.
LOL
That's up to developers, it's not something that MS can decide except for the games they own.....
No third-party developer will optimize for a ultra-niche device that sells like shit, that also runs PC games by default
The juice is not worth the squeeze
You run the PC version, adjust the settings and that's it....
You are still not getting it, there's a difference between having a preset in a PC SKU vs having fixed spec optimized Console game SKU. Sure, you can run the PC version for Epic and Steam, that version may or may not be optimized for Magnus, but for the Xbox ecosystem, you don't get certified for Console store if you don't use the GDKX.
No Xbox Console store version would mean no chance of Gamepass money bag, no xCloud reach, no free MS marketing.
And you are assuming the device will be niche based on your bias. AMD and MS are trying to take over the entry level and midrange pre built PC market.
