It's its size that makes it difficult to move. Some major ecosystem stuff is designed around the svn infrastructure. When the will arrived to make a change, it seemed natural to migrate not just to a different VCS but a different host. And this seemed to spawn a new debate: monorepo vs multi-repo. [still open AFAIK]

At the recent 2016 US Dev Conf, there was a consensus to move to git and that the new host would be github.

Really subjective IMO part: In general, there's tons of really smart folks working on really awesome stuff in LLVM+clang+etc. There's a handful of folks also focusing on the general "plumbing" software within and among those projects. The meta-plumbing job of the dev infrastructure is "kinda interesting" to several folks who want to improve the way the project is developed. But "kinda interesting" doesn't pay the bills and so it's a second (or nth responsibility) for the folks volunteering to work on it. Add to that the "no good deed goes unpunished" rule that they'll get the responsibility/blame after making a sweeping change, it means it will require extreme patience and caution.

Yes! Such work is all done on a volunteering basis, when we find time for it on top of the "real work" (bug fixes, features, ...). All the infrastructure work is not always rewarding, you just get the upset people yelling at you :)
