Why would they want to refactor their lexer? They're hard to get right in the first place.

Mostly, I'm curious about my second question. What's the state of testing the core of PHP? I'm totally unfamiliar with the implementation.

I understand that it may be dumb to refactor the lexer, but it gets less dumb if it's supported by hundreds of tests, and far more dumb if it's based on testing over time.
