> Php7 did nothing like that, that's why the "porting" process was so light.

This is nonsense, PHP 7 contains a long list of backwards-compatibility breaks:

If PHP 7.0 didn't break anything, it would have been called 5.7.

The upgrade is easy simply because these breaks do not have as much of an impact as Python's did.
