Note that it’s not “a little bit” of space.

i.e. the debug information is more than 4x larger than the code its for (!).
I agree managing the symbol files does become significantly more difficult in
this case but the patch makes quite a substantial difference to the number of
kernels you can keep in / (especially on older installs which have <1GB roots).
Perhaps there could be a flag to disable it just for the kernel that could be
put into /etc/make.conf? That way it’s set and forget if you are kernel
juggling.
