I think that each software should do one thing (and provide interopérability). I don’t think that copying solutions of big companies are a good solution as they have the people to maintain huge monolith that do a lot of things but I don’t think community maintained projects can maintain such softwares, nor do I think it’s a good way to welcome new developers.

I would rather like a simple link to matrix username in the bio or an integration with an existing solution with a unique identity.

Therefore I hope it won’t happen because it would complexify the protocol when e2ee private chats already exist.
