Yeah, I agree that somebody could possibly use them.
But the odd thing is, we don't actually export anything *useful*. It's
not like we export the define for __FD_ISSET() etc, which would be
something somebody really wants. No, that kernel header only exports
the (unused by the kernel) building blocks for creating __FD_ISSET().
And I suspect (but it must be before even the old bitkeeper tree) that
we *used* to implement __FD_ISSET() long ago. We removed it, and
nobody used it, so nobody even noticed that we removed it - but left
some now unused stuff behind.
