Well, that is obviously not true in all cases, since at least vq_gdos
is guaranteed to change register d0. If it didn't, it would not work
at all.

I just checked the ROM on my Falcon here, and the VDI there saves
d1-d7/a0-a6, but the AES only d1-d7/a1-a6 (well, the AES does save a0,
but only after moving usp there ;-).
NVDI also saves everything except d0.
