OTOH mount notification is way smaller and IMO a more mature

make sense.

But userspace can't retrieve the unique ID without fsinfo() as things stand.

I'm changing it so that the fields are 64-bit, but initialised with the
existing mount ID in the notifications set.  The fsinfo set changes that to a
unique ID.  I'm tempted to make the unique IDs start at UINT_MAX+1 to
disambiguate them.
