Yes... I agree this could be useful in other applications...

The problem is not so much old mount binaries, since they will fail
with something similar to "Unsupported nfs mount option: nordirplus",
its using new mount binaries with old kernels. The kernels
will silently ignore the option. One could tell the option is
not set by catting /proc/mounts (since the "nordirplus" would
not exist), but I agree there is potential for confusion...

But on he other hand I didn't want to increase the mount
version from 5 to 6 since I think that whole mounting version
stuff is just rats nest.. and Two, I really didn't mounts
to start failing (due to mis-versioning) for a option that
will probably never be used... But it is trivial to increase
the version, but it just causes so many headaches I was
trying to avoid it... Right or wrong that was the reasoning...
