Actually, I'd suggest that if no one wants to argue against it, make
all ports share exactly the same device switch.  That'll reduce

I can't think of any serious drawbacks to it.

If nobody cares to argue vehemently against it and presents a good
drawback, then i'd say it wins from the maintenance perspective.

I've heard you mention a problem, and try to give examples (some of
which i've replied to already).  I don't think you've demonstrated
that the need to do 32->16 and new->old conversions in the MI kernel

If you'd like to try more examples, well, go for it.  8-)
