Because it's simpler.

Good luck convincing anyone about that.  There are 378 undocumented
macros in admin/CPP-DEFINES, and probably 1000-2000 in use in src/*,
increasing that number does not seem such a hot idea.

This is not a valid proof.  Maybe people didn't want to complain, or
didn't figure out the difference, etc.

Still not too good, and a deviation from the normal style of not having
includes in the middle of the file.
