This would really be better done on a branch so we don't have known 
half-working code on the master branch that we generally consider to be 
production-worthy.

Would you mind pushing out a revert commit for all this work in progress 
and moving it onto a branch where it can grow and be discussed and tested, 
then merged in later?

Thanks,
Jon
