default context file should have one default context all of the other
types should be broken out into the users directory.

I disagree. We need defaults that work.

But the defaults are in the individual files which we now ship. So as I
add new user ABC_U type I need to provide a
/etc/selinux/targeted/contexts/users/ABC_U
And defaults_context will not work for that user if the ABC_U file is
not there. So it will not Just work.

If there is no default contexts specific to the seuser, the general
default_contexts will be used. It will cover people who want to add
their own seuser but don't add a seuser-specific default_contexts. It
doesn't hurt to have all of these entries in the general
default_contexts since all of the valid contexts are defined in policy.

But it doesn't help, and you end up with invalid context listed if you
do not have that user type defined.
So if I don't have unconfined_t or sysadm_t I end up with a bogus listing.
I say make it user_u and move on. I actually would get rid of the file
altogether and force all user types to have a user context file.

It doesn't hurt. The libraries have handled it for a very long time.

I'm not sure what you are saying. You would have to be missing all
standard roles to not be able to log in.

That would be an argument for the SELinux list as that affects the
libraries.
