The archive would ideally be recreated in this case. I read the ticket #19458 about merging images and archives, and I agree with the advantages, and overall it would simplify the code base. However, would we also consider rebuilding old images/archives?

This again raises the question of default behavior. I understand that the command should remain non-interactive, but when rev-upgrade isn't explicitly called (say when a dynamic library is updated, and it's necessary dependents automatically get rebuild), would it be intrusive to replace one's binary archives or simply rebuild one's ports by default?

Would MPAB just need to have it's snapshot be consistent at any given time or would it require a separate revision number for each port rebuild? In the latter case, I might want to consider building some support for automating the change of revision number rather than delegating it to MPAB to keep everything consistent.
