It is optional as well - so if one does not want it - just not turn that feature on.

If we decide that the benefits outweigh the risks and accept that differences (even though we’ll do our best to bridge the gaps) – we’ll have to make “Enabling” / “Disabling” an actual thing. being an experimental feature flag is not enough, feature flags are designed to be short-lived until promoted, or decided against.

The question then becomes more along the lines of:

• Do we want a toggle for Activity Pub at the Pod level? (I assume yes)
  
• Do we want a toggle for Activity Pub discovery at the User level?
