IMO your argumentation paints a little black and white. There are 
several options such as internal tags or branches
to avoid those drawbacks and solve all your illustrated use cases quite 
acceptable.

IMO it was already a problem within Zope 2  to manage your custom 
application and all different release cycles of the involved products.

Everybody who observed Zope 3 development deeply enough, should be aware 
of the circumstance, that their are still a lot of fundamental changes 
happen. Those changes are caused by growing perceptions of the problem 
domain. This learning process is only fuzzy predictable and therefore it 
is pure illusion to demand the same liability like in a software project 
within a more established state.

IMO it is a very costly and unsatisfying decision to stay with 3.0.0 at 
the moment. I would suggest to people who can't accept the consequences 
of early adapting a technology to stay with Zope 2 until the fundamental 
changes are gone, because you still would have to change your code even 
if theire are plenty of releases during that time. IMO it's also an 
illusion to belive the update-your-code-and-solve-all-your-problem 
script will be shipped within the release.
