Popcorndude added a comment. I messed with the constraints a bit, and it would be pretty easy to get up to ~50% with the constraints you outlined (the numbers I gave before may have forgotten to skip newlines, lowering the count). Adding + and * covers 3/4, and most of the rest could be rewritten without to much trouble (other than https://phabricator.wikimedia.org/P1793 and possibly a few others that are really basically impossible).
(\\.|[^(){}\[\]\\]|\{\d+(,\d+)?\}|\[(?!^)(\\\[|\\\]|[^\[\]])*\])* should work (though it does let character classes through). After a bit more fiddling: https://phabricator.wikimedia.org/P234, https://phabricator.wikimedia.org/P274, https://phabricator.wikimedia.org/P305, P353, https://phabricator.wikimedia.org/P395, https://phabricator.wikimedia.org/P428, https://phabricator.wikimedia.org/P529, https://phabricator.wikimedia.org/P866, https://phabricator.wikimedia.org/P998, https://phabricator.wikimedia.org/P1190, https://phabricator.wikimedia.org/P1256, https://phabricator.wikimedia.org/P1257, https://phabricator.wikimedia.org/P1472, https://phabricator.wikimedia.org/P1612, https://phabricator.wikimedia.org/P1662, https://phabricator.wikimedia.org/P1793, https://phabricator.wikimedia.org/P1986, https://phabricator.wikimedia.org/P2015 are the only properties where I don't see a way to rewrite the format with your constraints plus infinite repetition (i.e. no groups), and with a lot of these there probably is a upper limit, it's just that no one bothered to write it into the format. With that in mind, the list shortens to https://phabricator.wikimedia.org/P234, https://phabricator.wikimedia.org/P274, https://phabricator.wikimedia.org/P428, https://phabricator.wikimedia.org/P1472, https://phabricator.wikimedia.org/P1612, https://phabricator.wikimedia.org/P1793 (most of which are probably things you didn't intend to support anyway).
