Are custom emojis compatible with noStrudel? I replied with a banana ...

Reports are relatively common in more complete clients, too.

Private zaps ... if Damus and Amethyst use them, others will also follow. I just wonder what's the point to show private zaps others got, as they might have privately zapped themselves 🤷 Sure, if I got private zaps, I wish I would see for what and not only my wallet show funds received.

nip22 if widely used should also be easy enough and uncontroversial to at least display in other clients.

Post expiration might be controversial in the same spirit kind-1 editing is.

In the end I think most of the Amethyst features should be on other clients' todo list and they just haven't gotten to it yet. It would be good to have some research into who is missing out on which content. Gauge which account uses which clients and notify them if others are mentioning them in events they don't display for example.
