short answer: no

1) add -n <name> to the defaults of jail_<n>_flags in rc.conf and be done
    just now.  No need for a new variable.
2) you want to follow the new jail management on the freebsd-jail list.
    I would expect that there will just be no further changes to the rc
    script unless security related ones.

The new style version was never considered "experimental".  It wasn't
just not advertised that much due to the lack of 2) above.

Right, vnets are still considered experimental.
