Um... why are you removing the assertion that checks that it is destroyed on the main thread?

This is guaranteed by ThreadSafeRefCounted<DestructionThread::Main>.
I can keep it if that helps.
If useful here, it might be best to add such assertion in ThreadSafeRefCounted destructor instead of here.

Up to you, but I think I would keep it. Of course every assertion in the codebase should be guaranteed to never fail already... we have them because we know sometimes things go wrong.

Sounds good.

I don't think ThreadSafeRefCounted implies that the object needs to be destroyed in the main thread.

ThreadSafeRefCounted does not.
ThreadSafeRefCounted<WTF::DestructionThread::Main> does.
I kept the assert for now though.
