There are also already architectures in-tree that default enable it
today: frv, mips, and parisc. So at least the toolchain situation seems
to be sorted well enough for some people (admittedly easier if there are
fewer toolchain variants floating about..).

It is appealing from the embedded side at least, so it's forseeable that
most of the CONFIG_EMBEDDED users will enable it purely on the size
basis, especially since the tiny people seem to be mostly grasping at
straws these days..
