Comment (by simonpj):

 Looks sensible to me, although I am not deep into ABI hashes.

 '''Is there a single Note where the desired semantics of ABI hashes are
 explained?'''  Including the consequences for distros, which led to this
 ticket being created?  Then we could refer to that Note from here.  The
 comment "Do not allow filenames to affect the interface" just isn't
 enough!

 Even an inadequate Note would be better than none.
