Yes, we should generate the proper ftesting.zcml from grokproject, which 
is to use the new import location.

Yes, zope.app.securitypolicy imports from zope.securitypolicy (and is 
the bit that generates deprecation warnings). We should depend 
explicitly on both though. Eventually we can remove 
zope.app.securitypolicy again, but not this release, and with a clear 
message in CHANGES.txt and doc/upgrade.txt about what to do.

The general pattern:

* sometimes a package in Zope 3 gets renamed/moved, for instance 
zope.app.securitypolicy -> zope.securitypolicy

* the policy in Zope 3 land is to leave the old package around, but just 
make it depend on the new package and do a lot of imports from it. It is 
made so that it will give deprecation warnings for the people who use 
it, so they can adjust their code.

* eventually the old package can be dropped.

Now we did everything right, except for the last step: we dropped the 
package far too quickly. We should've simply kept it around.

Regards,

Martijn
