Thinking about scoping down coracle a bit so that I can do a better job focusing on what's special about it. Interested in folks' thoughts. What if I removed:

- Classifieds
- Calendars
- Public Groups
- Private Groups
- Rending support for obscure note kinds, relying instead on nip 89 handlers

I would hope to focus on more complete/correct support for relay and social graph management, as well as feed building and navigation.

My hope for the group features (including calendars) is that relay-based and MLS-based groups would be good enough to replace what currently exist.
