I was more worried that it's getting included from other include files,
and that the overhead is just the compiler front-end, whether used or not.
But you're right, it seems like this is one of the well-behaved header
files that isn't unnecessarily included everywhere ;)
So I have no real arguments in that case.

Yeah, we tend to include a _ton_ of stuff that we probably don't need to.
