I don't see how that is a "however". This situation is exactly right in 
my opinion.

Yes, having two Zopes is in my opinion completely unavoidable for the 
forseeable future.

I'm not sure what you mean here. I expect Zope 3 to keep the pieces it 
has right now, including the appserver bits. Nobody is proposing we 
throw away code, right?

If someone has the time to replace Zope 2's appserver with what's in 
Zope 3, then that would be good and we'll see that happen some Zope 2 
releases in the future. Calling that Zope 5 is not going to make it 
happen any faster.

"explosion", whether Zope 3 is going to be managed as a number of 
components or as a single story doesn't matter much for this. Presumably 
we'll still have Zope 3 releases that I can run, say, the 
documentlibrary on. For the component integrators (but that's mostly the 
Zope core developers) things will change. From the developer's 
perspective, and the deployer's perspective using Zope not that much 
will change - you'll still install Zope 2 or Zope 3. Perhaps the way you 
install it is different, but a Zope developer or deployer would 
typically still end up installing something that's called Zope.

I don't see how else we can get there than by the route we've been 
taking: continuous evolution with small steps. Saying we'll have Zope 5 
in the future which will include both still means we need to get there. 
I don't see how introducing a new name in the mix is going to help 
anyone, and I think in fact it will hurt. We make a commitment we'll do 
something, but nobody is actually signing up to actually do it in the 
foreseeable future.
