The easiest way to get a correctly working version is to extend `AbstractSet`, which provides a default implementation that works correctly.  As I think the default implementation is good enough and performs well enough, I saw no reason to fix the broken version.

The original ("broken") version has been working fine, and no bugs have been reported so far, and there would be a reason to have a custom implementation instead of the one in `AbstractSet` in the first place. 

I'm not against removing it, but only after we are certain that this implementation is no longer needed. 

Also, have you tried fixing it instead of removing it? If you have, are there any differences when you run the test with one or the other?
