Sorry you need to stop now .. the new format didn't work for lots of situations.
It has been a work in progress and is still evolving they only just fixed the sub interface issue.
The issue I am asking about is how do you deal with a vlan sub interface that you don't want to connect to the bridge. The only way you can do it is make an old school vlan interface and try and merge it with new format.
If you want to see the sub interface change discussion it's well covered here
