I think that sounds like a reasonable feature -- I can see people
getting annoyed at Emacs' behaviour here.  Perhaps the way to implement
this would be to:

Quit Emacs: `C-x C-c RET'
Save file: `n'
Delete auto-save file?: `yes RET'

That is, introduce a new option that would offer to delete auto-save
files for buffers the user chooses not to save.  This could even be done
generally -- not just during shutdown -- afer the

Buffer foo modified; kill anyway? yes RET

dialogue.  (This would be an opt-in user option, of course, because the
current behaviour is safer.)

Any opinions?
