I don't think Pleroma FE can work without hacking it since it doesn't support OAuth login to begin with. That's an L on their part IMO. You're right, the bunker stuff is underbaked. I'm still thinking on that. The obvious solution that fixes everything is to just allow username and password login. But it defeats the purpose of Nostr. So I don't know the solution yet. I will keep experimenting. In the meantime we should just make Soapbox work correctly.
