Hey Susan!

We haven't called a formal vote, but from my estimation consensus within
the project is opposed to adding a NOT operator. After our pending releases
are handled, I'm going to try to pull the reasoning into a more organized
document since I expect this will come up again.

Since I'd like that document to include some examples that can be
implemented as is, even though NOT seems like an obvious choice, I'd be
happy to help worth through how your use case can be handled without a NOT

Did you happen to already read my earlier approach[1]? I believe it can be
used to accomplish all of the scenarios you presented.
