Uh, how about: because the behaviour is an optional behaviour in a
driver that's conditional on the state of a boolean flag?  (Many
things are kernel options that arguably should not be, and fall into
this category.)

Also, how about: because you may want to change the setting of the
flag on a per pciide-instance basis?

Also, how about: because then it's patchable?  (OK, you could do this
with an #ifdef and patchable kernel variable, too, but "see above.")
