You’ve basically answered your own question already.
It wouldn’t make any logical sense to remove the After Effects option entirely, since WinTrust can still be used with older versions where it remains functional.
As for warnings within GenP itself, that’s ultimately up to the GenP devs, and if they feel it’s warranted, it may be added in a future update.
If someone doesn’t want that option, there’s nothing stopping them from simply masking it out themselves, and if it becomes enough of an issue, we can look at including that step directly in the guides as well, likely by providing a modified version with the option already removed so users don’t have to do it themselves.
That said, this introduces another issue, where people then question why there are multiple versions or why their GenP doesn’t have that option available. No matter what approach is taken, some users will always question it and not read fully.
As for warnings more generally, there are already multiple notices in the GenP Wiki that clearly explain the situation and that users should see if they’re actually referring to the guides.
Regardless of what’s written or how clearly it’s explained, people will still ask about it anyway, even if it was only discussed recently or was the last thing posted right before their own new post. Unfortunately, that’s just how it goes.
It’s also worth remembering that a significant number of users obtain GenP from third-party sources that simply rehost it for traffic due to its popularity, without providing proper guidance or support.
As a result, many people end up using it without fully understanding what they’re doing and only come here to ask questions once something breaks or their setup is already misconfigured.
