The only problem with a single #+PROPERTY: line is that this line could
become unreadably long. By allowing such an entry to span multiple
lines it becomes feasible to chain together many variables into a single
property. Another approach which is easily implementable would be to
use syntax like the following...
#+PROPERTY: var foo=1,
#+PROPERTY+: bar=2,
#+PROPERTY+: baz=3,
#+PROPERTY+: qux=4
#+begin_src emacs-lisp
(+ foo bar baz qux)
#+end_src
#+results:
: 10
Although I originally switched from the above to the implemented because
I thought that using a block would be more consistent with Org-mode
syntax. Also, the above is undesirable in its requires the PROPERTY+
lines to care about their position in the Org-mode file, which isn't
normally the case.
I think of #+FOO: lines as containers for anything that fits on a single
line, and as blocks as containers for anything that requires a line
break, e.g., #+HTML and #+BEGIN_HTML/#+END_HTML.
I didn't realize that there was an extra semantics of blocks as
formatting, and I'm not sure if such an association is desirable or
intentional.
