I didn't find a better name 5 o'clock in the morning.

I can't have unused code in our codebase. We have swiss banks as customers and can't pass their security assesment with such a setup. Belive me, it's not easy to fit their needs. > * If you're interested in replacing a few select views with > your own implementations, you can use ZCML overrides.

I think we will split packages in its base parts. For exapmle this means we will create a package zope.session that contains the python api and degrade zope.app.session to contain the zmi views. > My reservations toward to proposal aside, you also write: > > """ > But if we like to load only the component related > configuration without any view configuration, we could use > > <include component="foo.bar />" > """ > > Why do we need to change ZCML?
