I'm unsure why this is necessary.

I don't think I follow.  Wouldn't the whole home directory be
polyinstantiated, not just the .ssh dir?

This also seems odd.

Lets examine what is going on.  We want to allow the login programs to
populate a newly created directory from /etc/skel with proper labelling.
 If the admin puts /etc/skel/.ssh then this directory needs to be
created by namespace.init with ssh_home_t.

Yes, I know thats what happens.  I just got polydir and polyparent mixed up.
