So previously the loader would check compatibility against the
version of the FS module, and now we're checking against the version
of libsvn_fs_util? Hmmm, I'm not too sure that makes sense.

And when the FS module is initialised, we now check that the version of
libsvn_fs_util is compatible with the FS module's dependencies?

This definitely seems wrong to me - we aren't checking anything against
the FS module's version.

(Additionally, and this should probably go into a separate patch anyway,
shouldn't libsvn_fs_util be one of the dependencies listed in the FSFS
and BDB checklists? I think it probably should).

Needs to be svn_fs__check_already_open().

If we're going to say that this is appropriate for a general filesystem,
I'd prefer that this checked fs->path (as the FSFS implementation used to
do). There's no requirement that a generic filesystem assign anything to
fs->fsap_data, whereas there is a requirement that they assign fs->path.
