If there was no other way to get os.access-like functionality, I would say it 
should be backported.  But since there are other ways to figure out everything 
that os.access can tell you I say don't backport and amend the docs to state it 
is not Unicode-aware.  If one was adventurous enough the docs could even 
include other ways to get the same info when Unicode had to be used.
