There can be some benefit in mounting filesystems so you can see what
another user sees.  So I think it is worth looking at.

However all of the user that care are at best CONFIG_EXPERIMENTAL
for the next while.

Therefore as long as we have something that is close we can fix
the last couple of details after we have the bulk of the code
changes made.
