[Product-Developers] New style collections: migration, sub collections?

A few quick questions about the new style collections in Plone 4.2, to 
check that I understand them correctly.

Unless I have missed something, old style collections are not migrated 
to new style when migrating to Plone 4.2.  Does someone have code that 
would do that?  Perhaps an add-on that I missed?  If not, then I might 
want to create a package for that.

Sub collections are not possible in the new style.  I guess this is 
because the UI and the logic can quickly get confusing and you do not 
win much over creating a second, separate collection.

I am guessing that creating a folderish version of the new style 
collections should work though, allowing you to nest them.  Some logic 
would be needed that looks for a parent collection and combine the two 
queries.  That may not be good for Plone core, but are there technical 
reasons why this would not be possible?
