Well, #unload is a bit of a misnomer. MCPackage>>unload does what it says,
but most implementors don't remove themselves from the system, they just
prepare to be removed. That typically means unregistering from menus or
flaps, cancelling notifications and so on.

So if Trait>>flatten were implemented per Tobias' suggestion, then
Trait>>unload could call that.
