I agree in principle that it's a good approach. However:
1. letting code slip in after deadlines is not what held up 1.34.
2. You have to be careful that taking code out doesn't break more
stuff than it fixes.

That's a fantastic idea.

I think I disagree, though not strongly.

No it can't. The way it works is:
1. freeze CVS
2. convert it to subversion.
You can't (reasonably) convert CVS to subversion, work in the
subversion repo, and then somehow merge an updated CVS back into SVN.
Or did you have something else in mind?
The subversion repository is ready to go now.

I agree that's a potential danger. We should look carefully at what's
1. Regression testing doesn't use (actually, doesn't require) CVS.
Those optionally using CVS now can just as easily "optionally use"
2. Developers. What? Setting up passwords and accounts?
3. All other release process changes. What are they?
So far I don't see any serious issues. If you can be more specific
I'm open to chaning my mind.

I don't understand that last sentence.
