Yeah, the docs are already quite clear that you cannot push to the DRM
trees with normal git, and that you have to use dim. Not only does it
check and enforce all the rules in the documentation, but it also
rebuilds drm-tip and keeps other trees in sync, which isn't done with
a regular git push.

The idea I had a few weeks ago was to have dim use 'git push
--push-option fdo.pushedWithDim=this-was-pushed-with-dim-and-not-manually',
then have the hooks on the server side check for that option and
refuse any direct pushes. (Or at least, if people are pushing
directly, they have to _really_ try to be doing it, and can't do it by
accident.)

If someone types up the dim patch to do that and gets it committed,
after a couple of days' grace period for everyone to update I can roll
out the server-side hooks which refuse non-dim pushes.

Cheers,
Daniel
