Just to make sure: If we ever had a formal distinction of the
zope.* and zope.app.* namespaces, I think we've abandoned it a
while ago already. So, it doesn't matter whether a package is in
zope.* or zope.app.*, we need to take all interdependencies (also
the ones in zope.app.*) into account. So all in all I don't think
it's a big problem in zope.sendmail depended on zope.app.component,

So, you suggest to leave this dependency as it is as long no-one
zope.app.component.vocabulary.UtilityVocabulary to define a
vocabulary for the utilities implementing
So we'd suggest to move
zope.app.component.vocabulary.UtilityVocabulary out of the
zope.app.* namespace because it is a generic vocabulary.
Possible places for UtilityVocabulary could be zope.component
(because the concept of utilities is defined there) or zope.schema
(because the concept of vocabularies is defined there).
zope.schema seems to be the better place because zope.component
does not depend on zope.schema yet.
But zope.schema does in no way depend on zope.component.
Yes, you are right. So we would introduce a dependency from
zope.schema to zope.comonent.
The only way to get lost of the zope.app dependency seems to be a new
package "zope.app.sendmail" (including deprecation!). But there is
already a zope.app.mail which is deprecated and will be removed in 3.5.
