Or you could give your app users a choice to not use a nip implementation that is heavily disagreed upon.
Discussion
This NIP will be the cornerstone to some much of the new features coming up. You can't do a lot with urls.
What features could you possibly be implementing that involve memes and pictures posted on nostr that people want an opt out for?
A whole ecosystem for creators
Don't think Nostr is just a Twitter copy cat. Some people forget that.
Then let people opt in with images, you can clearly allow people to opt out like you did nip95
People shouldn't be locked into using that content ecosystem you want to create, especially if they just want to post a meme.
I support the direction you're going in here, in fact it'll directly help something I'm building, but I still don't see why you can't make that functionality optional.
Add a settings menu and let users choose what functionality they want to enable.
Opting out of nip 94 for images should in no way break future functionality. You can clearly code this because you made nip95 posting optional.
