No. Because the user might have the RPM installed (thus the post-install
would get triggered on update), but may in fact be using nbd.

We'll have to make the drbd we ship default to the old major/minor and
also keep the examples consistent with that.

However, we can advise them use the different major in the future, but
for a GA'ed product, we cannot break what is essentially the ABI to
userspace.
