This series is OK for me. I recommend installing at least all the
infrastructure changes now.
I'd seriously consider adding the one converted case in vector.md once
the prereqs are ine. It provides a clear example of what these bits are
supposed to be doing and gives us some superficial testing while the
rest of cases are converted.
