I have two issues with Persona being on the back burner that affect us
greatly and one that might affect us but might not:
1. no one is working on it full-time anymore
2. as new versions of things are released (iOS, Chrome, IE, ...) and new
issues come up, it's not clear they will be fixed
3. goldilocks future is uncertain--we were waiting for this I think
Items 1 and 2 are a big problem. Sure, Persona is open source and we
could all go hack on it, but I'm not clear on how changes we make could
get to production.
Item 3 might not be an issue. Mike Kelly is going to change
django-browserid so it ignores the .watch() stuff. So depending on what
our specific issues with .watch() were, we might be fine.
Given that, while it'd be great to join the rest of Mozilla and use
Persona, I think it'd be a huge disservice to the Firefox user base to
switch.
Given that, we should ditch it and reduce the complexity of what we're
maintaining and testing sooner rather than later.
