PSA: Vim is one of the most stable software packages I've ever used, and if I pick an arbitrary version from the source code, I can "make install" it and it'll very likely Just Work. For the time being, I simply plan to not "git pull" and keep using the Vim version that I have.
The only problem I can think of is being unable to compile it with newer versions of external interpreters, I'd consider looking for pure vimscript alternatives to any python or ruby plugins you might be using.
