No examples online before 2023 seem to work?? e.g. NormalizeNamespaceByPSR4ComposerAutoloadRector

[hopeseekr]

    $rectorConfig->rule(NormalizeNamespaceByPSR4ComposerAutoloadRector::class);
    $rectorConfig->rule(NormalizeNamespaceByPSR4ComposerAutoloadFileSystemRector::class);

doesn't work because neither class is still in the code base.

I can't for the life of me figure out how to fix PSR4 issues in current rector v1.2...

I have scoured teh internet for how to do this, with no luck.

Please help. This is just one of many examples.

Hey, this rule was removed because it worked only half-way.
The namespace were changed, but then class references stayed the same.

We use IDE class-move or this command as a replacement:
