Actually, there is no real need for a new namespace. There is only one name clash with Simple English Wikibooks content in the Transwiki namespace: a redirect to a book that is nearly identical to the one at Simple. The two are so similar that we'll either merge the two or delete the lesser one.

See ongoing discussion at [[b:Wikibooks talk:Simple English merger]].

I should note that a Simple namespace will conflict with the Simple interwiki prefix unless that is disabled on English Wikibooks.

I've just deleted [[b:Transwiki:How to learn a language]]. We can now move everything over. Delete what we don't want, merge what may benefit existing content, move non-simple books into the main namespace ([[:simple:b:Geology]] is hardly simple) and decide what to do with the rest (new namespace?) in our good time.

I withdraw this bug as it seems it does not have community support behind it. Should this change it can be reopened.
