I don't remember having that much trouble when we started ceilometer. What

We do this sort of risk assessment all the time. For internal projects at
DreamHost (and I'm sure at other companies), we lower the risk by having
more than one developer who understands the code. For OpenStack
requirements, we look for a healthy and active development community
supporting the library. Applying similar criteria to new OpenStack projects
seems perfectly reasonable.
More specifically, I would like to have the commitment to a potential new
OpenStack project spread across more than one company. We've recently had
IBM ask to withdraw a driver from nova because they changed directions
internally. I wouldn't want a change in direction (or profitability, or
whatever) in a single driving company behind a project cause it to fail.
The question is when to put that "diversity" requirement in place.

Yes, hence this email thread. :-)

I have more of an issue with a project failing *after* becoming integrated
than during incubation. That's why we have the incubation period to begin
with. For the same reason, I'm leaning towards allowing projects into
incubation without a very diverse team, as long as there is some
recognition that they won't be able to graduate in that state, no matter
the technical situation.

What data are you citing? We haven't done this very many times.
