Kind of sort of. It's actually a timing dependent thing that can lose to stuff. If you just do a normally timed 2A it gets blocked by OS, you call out like 2A >2A which is a lower reward option but is more likely to catch. There's that back and forth.
With TRM and the fuzzy jump OS you have to actually consider if that person is going to hard call out your OS for higher reward. TRM comes from a failed throw tech, but the way you do this OS that's a layer. Then when you layer jump into it you have to add additional risk. So you have to decide if you want to OS to be safer vs the strike/grab mix up or not OS like that to avoid the high reward call out. It's more than a failed grab because that can lose to way more, this is specifically the OS losing. The only downside is that normal throw teching is pretty weak, but you're going to be opting to use it to react to different types of grabs where you're not wanting to risk buffering it. The big stuff is that if you are barriering, that's a different situation than blocking, and then you have to factor in things like fuzzy blocking and jumping along with it. You could probably write a paper on how barrier and TRM interact on top of things like jump and fuzzy stuff.
Shield throw is definitely the same thing. You can attempt to tech in the normal way which has higher risk vs the basic mix up, or you can try to shield tech which has higher risk attached when it gets called out. There are extra decisions to be made there based on the OS options existing, especially when you factor in other options. At some point you can hide tech inside of mash and backdash too, but again it's all different risks you have to think about. If you want to default to shield over normal tech that is fine, but you're defaulting to a different type of risk. You'll see people start teching without the shield once they get called out enough, plus shield specific call outs like delay grab and assault exist but lose to other OSes such as fuzzy mash and 3C tech respectively. Even if you decide to always OS throw tech behind something, you will always have to consider the additional risk of what youre hiding it behind. Plus you'll have to see if your opponent is doing OS specific call outs which can lead you to choosing options that are normally risky but now offer better reward, like instant mash vs delays.
In SF4 the big difference is that crouch tech is just way better. Instead of it being a 4th option that you're not going to risk, it's really just the catch all that needs to be very specifically stopped for the same reward. Most other OSes alter risk reward in a way that adds something and can be chosen or not chosen. Crouch tech in SF4 doesn't really change the risk/reward like that, it's less risk than almost every option and will almost always yield higher reward. That's whack.
Like I don't get what you're saying when you say no extra considerations are made when you have to consider the individual risk reward of the OS specific options. That's a pretty big difference to factor in. I feel like that's you personally just saying you don't consider those New things. Like, yeah, you think about them similarly to how you think about other options, but they def alter the risk/reward game you are playing and add more things to think about.
