Yeah, and get something that won't build. If there's any point
to this work at all, it has to be that we'll maintain the closest
possible buildable approximation to the last released version.

I don't think it's a problem. If we haven't committed anything to
branch X in a month, it's likely not interesting. It might be worth
having a way to get the website to show results further back than
a month, but that doesn't need to be in the default view.
