Kind of surprised that these are override and not final. Maybe still a confusing area of C++ for our coding conventions?

Not new: Seems like Vector should have this operation instead of it being two function calls.

Not new: Does this require that "none" and "manipulation" be earlier in the enumeration than any other actions? If so, then maybe static_assert that here?
