Processor `CleanUnusedComponents` gets slow between tags 4.7.16 and 4.11.1

I upgraded from tag 4.7.16 to 4.11.1 and realized, that there is a new option in the CleanUnusedComponents processor. Formerly it was always on and we used it at any time. Now it disabled per default. So to get the same result as before I enabled the processor. When enabling it gets noticeably slower than before.

When I make a code diff I can see, that the only responsible change is the use of OpenApi\Processors\Concerns\AnnotationTrait instead of formerly call of OpenApi\Processors\Concerns\CollectorTrait. I don't dive deeper, sorry.

The result of our cleaned documentation is the same when changing the version. So it only gets massively slower? We use the generation of our API doc in a git-hook but with the newer versions we couldn't go on like this.

Yes, that seems to be an issue for large projects. The new version of the trait does a lot more work. Hopefully there are some more optimizations that can be done.
