From the software's point of view the drives are
the same (with different

80 tracks of 15 sectors double-sided and imaged a 1.2MB 5.25" disk onto it
for use with IIRC DOS 3.2 that didn't support 3.5" drives and it booted
from that disk and worked just fine treating the 3.5" HD drive as a 5.25"
HD drive.
yes
trivial correction:
3.20 supported "720K" 3.5" (also some OEM modified MS-DOS 2.00 and 2.11)
3.30 supported "1.4M" 3.5"
I used "720K" 3.5" drives, even down to PC-DOS 1.00 !
(but, my primary interest was reading sectors, and then parsing file
systems)
