You don't have to, other than avoiding stuff like this, or for the
additional features.

While all the guides seem to be written around grub2-mkconfig you can
still use grub the old way and just create your own config file.
Grub2 is more flexible in terms of supported filesystems and such -
which is helpful if you're using lvm, mdadm, btrfs, and so on.
However, I don't think it accepts the old config file syntax so there
is some effort required to migrate.  You'll of course want a rescue
boot device (but I'd say that applies whether you're migrating or
not).

I started out with a grub1-like approach and ended up moving to the
grub2 style.  I just install my kernels with make install and then let
grub2-mkconfig set up my config files.  The only issue I found is that
if you're playing with git kernels it doesn't always order the
versioning right (a.b.c+ isn't > a.b.c and things like this).
However, you can add your own rules to get entries auto-created which
can be helpful.
