I understand wanting to bundle things into AP. Let’s fix the core and not abandon it, right?
But the use case here isn’t in ActivityPub. It happens when I’m visiting a website OUTSIDE of my home server. It’s how we see 90% of the internet.
So building this feature into AS doesn’t make sense.
These interactions need to tie more deeply into Fediverse servers in the same way that the FB “like” button does. That’s what FEP-3b86 does.
