This seems fantastic - why can't this be committed?  Surely if it's
committed then the flaws will fairly quickly be ironed out?  Even if it has
flaws, then if we say 'this function is not yet stable' at least people can
start testing it and reporting the problems?

Is it a maintenance headache just for you to keep it up to date, or how
would it be a maintenance headache if it were committed?
