We don't yet have inline expressions for \if so the ready-made boolean is a convenience.
Oh, that seems a bit sad, but I guess it makes sense.
I agree, but there hasn't been much appetite for deciding what expressions would look like, or how we'd implement it. My instinct would be to not create our own expression engine, but instead integrate one that is already available. For my needs, the Unix `expr` command would be ideal (compares numbers and strings, can do regexes, can do complex expressions), but it's not cross platform.
