This has been discussed, weighed, and we decided to go ahead with this
syntax change.
The restriction is not unnecessary:
1. Org syntax is not just used by Org in Emacs. We have a more general
syntax definition (https://orgmode.org/worg/org-syntax.html), aimed
at submitting as RFC.
2. Supporting arbitrary property drawer position will increase the
maintenance burden. Your patch will not cut it. Basically, we will
have to parse the whole section to determine if a given match to
property drawer regexp is real (it may, for example, be a part of src
block or example block). Moreover, org-element-cache will have to
adapt in non-trivial ways to handle such property drawers.
Instead of modifying Org syntax, it would make more sense to implement
"dynamic" heading properties that can be calculated according to
arbitrary defined function. AFAIU, it will also achieve what you need.
