No, that's not backwards compatibility.  That's doing something just
because that's how it was done before.  There is no reason why your
CDs wouldn't work just as well the other way up (in fact that's how
they are in all CD players in HiFi systems I've seen recently; at
least one car autochanger has them the right way up as well, and at
least one has them vertically).

Backward compatibility is something like supporting tapes as well
as CDs.  I wouldn't get a CD-only player for a car, because most
of the things I want to listen to while driving are on tape rather
than CD (and those I have on CD I can easily put on tape anyway).

In the same way, I wouldn't bother with a 'DOS' which couldn't 
run my existing applications.  It wouldn't be DOS.  It might be
'better' in some ways, but would also be useless.

Like the CPU, you mean?  That seems to be most of what people
complain about in DOS...

A 32-bit DOS would have to maintain some way of running an 8086
style program to be compatible, and that will cause bloat and
likely still not be fully workable (many DOS programs access
hardware directly, for instance, particularly for comms and
video).
