Yeah, the implementation is huge part of the details, though.  Unseen is
handled special; every program would have to be changed.

I'm ... confused?  AFAIK, the MDAs just pipe it into rcvstore, which
does update the sequence.  I am aware that procmail can write to a
MH folder directly, but it can also just pipe to rcvstore.  I'm trying
to understand the use case where "use rcvstore" isn't an option, because
it would require a LOT of careful surgery.
