After reviewing FEP-5624: Per-object reply control policies and GoToSocial's interaction policy spec, I find myself leaning toward the latter for long-term considerations, though both have merit.
FEP-5624 is admirably focused and simpler to implement, which I appreciate. However, #GoToSocial's approach seems to offer some architectural advantages:
The three-tier permission model (allow/require approval/deny) feels more flexible than binary allow/deny
Separating approval objects from interactions appears more secure against forgery
The explicit handling of edge cases (mentioned users, post authors) provides clearer semantics
The extensible framework allows for handling diverse interaction types, not just replies
I wonder if creating an #FEP that extracts GoToSocial's interaction policy design into a standalone standard might be worthwhile. It could potentially serve as a more comprehensive foundation for access control in #ActivityPub.
This is merely my initial impression though. I'd be curious to hear other developers' perspectives on these approaches.
