Yeah, certainly we lack badly for developers, and a lot of the XDC
discussion was on how to make the codebase more approachable so we can
get more testers, casual contributors, and full-on developers involved.
We've got a long way to go.

One of the suggestions was to get people more involved; if you see a
review go past, just dive in and review it anyway.  If you can't review
it because of a lack of context, go back and ask them to document the
relevant area.

Sure, but in reality, very few people end up actually regularly running
master, just because of the breakage.  Even if it ends up going really
wrong, we end up blindly merging branches we can't really test, and we
at least get some modicum of review, with some additional amount of lag
between commit and master.

Heh, sure. :)

We had broad agreement that we wanted to merge the drivers in, but if
all development is being done directly in master ... what are the odds
of having the core server, rendering, input, modesetting, and your
particular driver actually working?

So, at least from my point of view, locking master off is basically the
only thing that actually makes it possible to merge the drivers.
