Thanks for the patch.

Typo: enhance.  And as a convention nit, it should be capitalized.

IMO the let-binding doesn't add any clarity over

  (nth 0 (split-string s))


I wondered about possible duplicates, but it looks like
org-buffer-property-keys already takes care of that at the end.

I think this patch is a clear improvement as is, but in the context of
completion (and the stack exchange post you link to), isn't the handling
around *_ALL keywords still a bit off?  It seems a caller would want to
complete without the _ALL; to use the example from that post, with
"#+PROPERTY: GENRE_ALL ...", the caller would want to complete "GENRE".
Is it worth providing special handling here?
