I think that you missed the point of the extension.

The point is clear, it's to synchronize a specific file system instead
of all of them.
But actually doing that from a program is harder than it looks, because
programs work with files, not file systems. To make this feature useful
the program needs meta information it can't easily get. That was my first
point.
I had a program, actually a set of programs, which test a file-system.
And this set of programs needed such a feature quite a lot, to sync the
FS which is being tested and nothing else - for both performance reasons
and to put more stress to the FS under testing. We used -o remount, rw
for this - but this forced us to run under root.
IOW, there are programs which take a mount point as an input parameter
and want do things with the whole FS, not only individual files.
