Allow exceptions to "Direct PHP files access"
I'd find it really useful to be able to add exceptions to this rule by specifying specific URLs you want to allow direct access for. For example AJAX calls to PHP it might be necessary to have.

The new feature is great, but broken PageLayer plugin (200,000+ downloads). For that specific case, I've also asked for a workaround to developers: https://wordpress.org/support/topic/direct-php-execution-blocked/.
