nnml in .newsrc.eld : not qualified as others e.g nnimap

[Richard Riley <rileyrg@googlemail.com>]

I have

,----
| (setq gnus-select-method
| 	     '(nnml "local"
| 		    ))
| 
| (setq nnmail-split-methods
|       '(("root-email" "^From:.*root@.*")
| 	("local-email" "")))
`----

The .newsrc.eld entries are of the form:-

,----
| ("root-email" 1 nil) ("mail.misc" 1 nil)
`----

I have some code elsewhere which pretties up my group buffer which
relies on the "fully qualified" style of .newsrc.eld entry e.g

,----
| ("nnimap+riley:INBOX" 2 ((1  etc
`----

Where I can grep out the server name and the type.

I did try setting the nnml backend as secondary but it still wrote the
non qualified style.

Is this on purpose? Can I enforce the "fully qualified" style?

Also, as an aside the split rule does split to root-email but is not
putting the rest into "local-email". I took the example from the
docstring/gnus manual and modified it. Again, is this some silly error
on my part or something more complex? Possibly something written into a
config file on the nnml backend?
