Have it disabled by default.
I don't think it's useful to have them for everyone i.e. the average
user.
What do they gain with it?
If you want to debug real grub you need qemu/bochs and gdb isn't that
easy (for the avera users)
Ok maybe I think still more like a Windows guy and not a Linux one, but
with Opensuse and Ubuntu I think Linux gets more attractive to people
who aren't that experts as we are here on the list :)
Why should we waste a bit of space by default for every Linux
distribution?
I doubt they all figure out that they can just disable it on creating
there .rpm etc.
And I doubt Robert is disabling this for the Debian build if it's by
default enabled on upstream ;)

For debugging it's always the best if you compile with -O0 too and this
shouldn't really be the default.
For the few people who need to debug real grub it shouldn't be too hard
to just recompile it with `CFLAGS="-g3 -O0" ./configure --enable-debug'

Having debug symbols in the userland tools could be maybe a bit useful
for example in the case of the grub-probe segfault I experienced on my
mdraid experiments.
