Interesting to know, but... man... they've got some opportunity with PHP hitting a 7.0 and there not being a WP 5.0 released yet.
Upgrading PHP isn't just about using "new features" - WP doesn't even have to use any new stuff, but still require higher versions for security and speed benefits would help move the web forward a lot.
