Hi, I wrote the blog post and wish I'd just written your exact words instead.

A lot of the lab PoCs still use contrivances (ignoring the ones that are disabling ASLR or just inserting `vulnerable.php` files on the server) that you don't really get in the real world - even the requirement of having to heap groom the same PHP worker repeatedly and sequentially is quite hard to exploit if the website has traffic. (this is why some of the slop PoCs reconfigure apache to have one worker, or pin WORKERS-1 with infinitely long requests).

This is in stark contrast to other, more severe vulns that the internet has seen (and will see in the near future) where there's effectively a blank cheque to fuck anything that is unpatched. This is not a blank cheque. It is still bad.

This doesnt matter though - luck and statistics are not serious security walls. Patch your servers.
