>you should not have double-negative //

Hmm, I'd like it if that always made sense, but sometimes the default state, with nothing active, is for Foo to be on. So "Disable Foo" is doing something not normally required, or something most people don't want. Sometimes it does make sense that _not_ performing a reduction in Baz is default, and that default is off.

You could probably solve it by renaming a feature to used an antonym, but not everything has an antonym [that people know, or that makes sense].
