No, but we try to restrict dependencies as much as possible.
The fact that these are generally useful means that they wre someone
likely to depend on each other.  For example, zope.interface is obviously
widely used. The zope.testing package is also widely used.

When we are initially developing something, it's hard to know whether
it will be generaly useful.  We try very hard to avoid premature
generalization.  We also have a rule that anything that depends on
zope.app must be in zope.app.  The plan and expectation is that, over time,
many packages will migrate out of zope.app.  I expect that, eventually,
zope.app will be much smaller than it is now.  That shrinkage will happen over
time has people have motivation and time.

Yup, we've done a lot of work.

There is certainly cruft there, but we've trie dto keep the
cruft/real ratio low.
