Yeah. A real solution should just create and overmount results. Unfortunately, AFAICT it's currently impossible to create a mountpoint with no underlying dentry or to overmount a symlink, so this can be a bit awkward. >>> - SCRATCH_MNT needs to be in /etc/fstab.

Sigh. If $SCRATCH_MNT is specified, then the line in /etc/fstab is unnecessary. If $SCRATCH_MNT is not specified, then /etc/fstab will do the trick. What does not work is specifying $SCRATCH_DIR [sic] but not adding an fstab entry.
