Well, combined with making it global, yes.
I always found developing a minor mode where we add and remove hooks to be
a bit of a pain, because you can easily end up with different buffers have
different state during development. On the other hand, if you have a
single global hook, it's either there or not, just whether it works or not
is dependent only on whether the minor-mode is on or not.
Seems a lot nicer to me.
