What does this team do and how would someone go about getting on it. I'd be more than happy to set up a 3.12 server and run it and see how much i could break it.

We appreciate your offer to help, but at this point, we're looking at a fairly limited testing of it to work out any major kinks before general release. We will consider your generous offer to help should it become necessary to increase our private testing of it in the future.
