Realistically, it's going to take us a little while to get everything working smoothly with this new process.
It depends. I think it is important to have a clear how-to page that describe the process.
But we might as well dive in and get started. It's a big change, but I think it's flexible enough that we will be able to adjust the process if necessary, and we won't end up in a 3.3alpha modules situation.
Squeak evolved a lot since I started to use it. I do not thing that big changes are bad if they make life of people easier.
I will set up a new swiki page covering the new process, as a point of reference.
I am willing to help.
