Here's my take:
First up, I'm somewhat dubious about the economic viability of updating decently functional games with remasters; I dunno it seems a bit like factory busywork that is generally low-risk, low-reward if you have teams set aside to specialize in this sort of development.
Setting that aside, I don't really have an issue with it. Even if it runs worse/is more demanding than the original, in a few years time that problem will most likely sort itself out through all-round advancements in tech. So, taking the long view the game will stay viable longer and potentially be better.
Creatively, I'm ok with it so long as the original work is respected. Games, in fact code generally is designed to be iterated upon and improved over time so its not like its some sort of holy text that's being defaced. Although obviously any change is likely to be divisive, and I would never accept change to incorporate contemporary fads and politics as that sort of editorializing is always destructive. But if its done with care and respect... go for it, because...
Here comes the hottest part of my take: I don't care if the remake displaces the original. Because if it does that, it makes the original work more valuable and desirable.
See, I always give people talking about "game preservation" side-eyes because it seems to me they just want "more stuff", or are somehow fearful of losing something.
That's not the mindset of a collector or an enthusiast; that's just hoarding.
Rarity = Value. And there's a huge difference in value between items that only survive in small quantities and mass-produced tat that ends up in landfills. And I stress I do not mean "value" in a purely monetary sense, I mean in totality like when a certain experience is uncommon to vanishingly rare in occurrence,
It bugs me to no end when something no longer being easily available gets hyperbolized into it being non-existent! Its bullshit!
