We had this problem on the desktop a while ago, and we worked with the
snapd team to solve it by introducing an extra option on the mounts
which snapd creates, called "x-gdu.hide". Parts of the GNOME desktop
respect this, and so user interfaces are not cluttered up with snap

This feels to me to be a cleaner approach than saying that *all*
squashfs filesystems should be hidden by default - instead, the software
which creates the mounts is able to communicate this fact and if you've
created your own mounts then you carry on seeing them as normal.

There's still the question of creating an interface to hide based on
mount options and how to set the default. (Personally I agree with Seth
that the systemd style is a nice way to do it, if upstream are up for
that.) But this warrants consideration, I think.
