I think that if just registering it under the same name solves the
immediate issue, that's the one we should just go for.

My reaction to that is "only if it turns out we really need to".

It sounds unlikely that somebody has an old ntfs setup and then tries
to mount things rw which didn't use to work and things go sideways if
that then suddenly works.

But "unlikely" isn't "impossible", of course - it's just that I'd
suggest we actually wait for that report to happen and ask what the
heck they were doing and why they were doing that...
