That sounds way better to me. It's just a matter of modifying the
following part in `org-set-regexps-and-options'.
#+begin_src emacs-lisp
((equal key "PROPERTY")
(when (string-match "\\(\\S-+\\)\\s-+\\(.*\\)" value)
(push (cons (match-string 1 value) (match-string 2 value))
props)))
#+end_src
If we want to be a bit more future-proof on that side, we may even
refine the `org-accumulating-properties' idea by making it an
`org-accumulated-properties-alist' where key is property's name and
value a symbol describing how they are accumulated. That symbol could
be, for example `space', `comma', `newline', `consed'.
