That's a different situation.
You probably meant to say: If aa["theKey"]++; doesn't fail, why should aa.remove("theKey") be special?

This is stupid. Part of the point of built-in AAs is to avoid to import things. If I need to import (or worse define) that discard template in all programs where I use an AA, then I will create my own AAs and I'll just import and use them in the first place.
