I think this should be avoided if we can. The idea is to lose the 
dependency of the zope.app.* packages for the ZMI, after all.

Of course there are exceptions: if you rely on a zope.app.* package that 
hasn't really been moved to zope.* yet (zope.app.form.browser for 
instance). But relying on zope.app.*.browser should be avoided in most 
cases, otherwise we create circular dependencies.

But the ZMI is all views, right? What is persistent?

For BBB, you want the zope.app.*.browser packages to import from 
zmi.core, not the other way around. Otherwise we don't clean up 
dependencies at all.

I think this should be done; if you update a zope.app.* package to 
import its ZMI stuff from zmi.* a new release of the zope.app.* package 
should eventually be made, and it should have a new feature release (so 
increase y in x.y.z).

For that, you might want to investigate the z3c.recipe.depgraph recipe 
to generate dependency graphs. To try it against trunks you need to add 
them to 'develop' in your buildout.cfg

I don't think you're slow at all. Your plan sounds good and I'm glad you 
have Roger giving you feedback.
