What happened to ReplaceAssertArraySubsetRector.php?

[eelkeblok]

I hope somebody can shed some light on my confusion. I'm trying to use Rector for a conversion/update of a bunch of tests. I ran into the use of assertArraySubset and was happy to find #1025. However, looking in the current codebase, I can't seem to find this. Am I looking in the wrong place, was it removed on purpose, or was it overlooked during some refactoring (as the project structure seems quite different from then)?

Thanks for any insight you might have.

It got removed here: #4611. Haven't found where its replacement (the polyfill) went.

So it did make it to the separate PHPUnit package. #5905

Right. So there... rectorphp/rector-phpunit#222. Not looking forward to handle all these cases manually.
