Well I can ignore the Rust part as much as I ignore the C serdev part...
Honestly, I need to find someone else to maintain all of it as I don't
really have the bandwidth. I don't think we should split it though.

And I don't have a tree for serdev. Greg picks up the serdev patches. If
the Rust folks are fine with them, then I am.
