It provides control over the set of files that can live in a given
filesystem, based on their security types (equivalence classes).  As you
are now creating device types in a different filesystem type, further
allow rules are needed to allow that association.

The more important issue is that fscontext= lets you set the superblock
security context, not just the root directory context.  restorecon can't
do that.
