I know that I will be testing it with a number of real world apps.

Let's not set the bar here higher than what we have for all other RFCs.
It's not as if we test the entire planet codebase every time we make a
potentially dangerous change, and PHP 7 has plenty of those.
We test a (fairly representative) sample of real world code through some
real world apps, framework tests and our own test suite;  Additional list
members and users will test it with their apps and provide feedback, etc.
