I'm not entirely sure anymore why I asked :) Maybe I considered to guard
against it using an assertion.

Does it really depend on the capabilities of the store, though? Between
loading an Association and removing a RowKey from it, all is in our control
(and all in one thread). So if we invoke Association#remove() for a RowKey
which isn't present in the loaded Association object, it still seems fishy
to me.

Note that's different from trying to remove an association row in the store
actually, there it may be gone already of course.
