what you are saying is not correct
Programs ignorant about the 23 bit DISKIO access, must set the MediaID
(#f0) in register C like usual.

they will work ok because they set the MediaID in C.

32 bit sector access requires a kind of new MSX standard; probably a new
diskromentry.
That also means that DOS has to be modified in order to use that new
entry.
Perhaps that can be done in future when a new DOS3 will be made... if it
will be made.
As you can imagine, 32bit access is not for tomorrow. But no problem,
because I DON'T think that 32bit access is the thing that is most needed
in the MSX community.
We can better spend our time creating games and utils.
