Sure, you're right. My point was just that the decisions you mention
should be made in the open by discussing the issues on the mailing
lists (as I believe we are doing). I still expect those involved to
come down to the group of interested engineers as you mentioned, who
would be able to obtain a suitable consensus on how to move forward.
I would just hope that these days such a group would not be
constrained by the companies the engineers choose to work for. I
think we're starting to get there and doing so has advantages for all,
whether at Sun, Google, Red Hat or elsewhere.

In some cases, yes. IcedTea has a hefty pile of patches, but we're
trying to push most of them upstream. There are obviously ones that
are too specific though and which it wouldn't make sense to send
upstream, and I'm sure the same is true at Google and Sun. Of course,
all of ours are there for all to see :) It would be nice if others did
the same too, a public Google-maintained OpenJDK forest seems a nice
idea to me.

It's certainly not on the scale of a distro, nor is it simply an
aggregator. It does depend on external code, just like pretty much
any significant project. Anything else would be recreating the wheel
and thus bad software engineering. There is also a heck of a lot of
new code being created here, which isn't true of distros (or shouldn't
be in any case!!!!)
The jdk, langtools and hotspot repos are developed locally. JAXWS,
JAXP and CORBA are all imports (from Glassfish I think). I think in
the long run it would be better if these were handled as such (as has
been suggested on one or other of these lists), rather than
maintaining the numerous local copies. I do know there is a plan to
pull from upstream before JDK7. I don't know if patches ever go the
opposite direction though.
In turn, IcedTea is aggregating OpenJDK with other stuff too of course
