Why would anyone shoot FD lenses on EOS film bodies
If they are going to lose autoaperture? That's what
Would have happened back in '87 even if Canon
Somehow allowed FD lenses to fit their EOS film
Bodies.

Secondly, I only gave one example of why FD
Compatability was abandoned, there have been
Others.

For example, what is the default mode of FD
Lenses when not mounted on a body? It is
Wide open regardlesso of aperture ring setting
Like M42 lenses or is it stopped down like PK
Lenses? If it's wide open like M42 lenses there
Would be no way to stop down on a EOS body because
FD lenses don't have AUTO/MANUAL aperture mode
Switches like pentax M42 lenses do.

Irrelevant to the discussion.
The point is, people can use M42 bodies on any K mount camera, inclding 
DSLR.
Whether it is convenient or not in't particularly germaine.
Your rational with Canon, if carried over to Pentax would be that M42 
lenses would not be usable at all on K mount bodies.
