What about the bus mouse cards with the din connector? Are they functionally identical to a com port?

Also as you have pointed out in the past, even on 386/486 Baby AT boards, PS/2 mouse support is lying dormant in the keyboard controller. And it's also in the AMIBIOS already, except that when the board manufacturer built the BIOS using AMIBCP, it gave them the option to permanently suppress PS/2 mouse support, and the ID string gets updated accordingly.
And for aries-mu's sake remember the "prebuilt" form factor of this era with ports on the back and a riser card for expansion cards is LPX, vs. Baby AT for custom built systems. It wasn't until ATX when they would re-converge.
There were a ton of cases which took baby AT form factor motherboards and LPX power supplies. "Baby AT" has a very specific meaning when if comes to PSU but most people use it to refer to LPX form factor supplies.
This is baby AT:
Just like standard 5170 AT supply minus the overhang part on the left
