You said "deallocating unreferenced elements". I thought you meant
elements unreferenced by the AA.
What I mean is, the AA isn't going to change implementations where it
now deallocates values that may still have existing references. If
that's the case, we can state that in the docs.
Removing a key does not deallocate the value that was removed. The
value's lifetime is managed by the GC and will be alive until there are
no references to that value.
