.... a patch for per-page ACLs ....
- Would you revert such a patch: Yes or No?
[...snip...]
So no, I would not accept such a "patch". Ongoing work to move in that direction, _maybe_ _possibly_. But some big honkin "patch" would be inherently useless crap.
Fair enough, and good answer!
So, if you want such a thing, use as-small-as-possible incremental updates, with lots of visibility and prior announcement and opportunity for review, and don't introduce dead code / functionality that isn't being used. Plus the other standard stuff listed before (clean code, etc etc) - i.e. don't give any technical reason to say no.
And remember, nobody said it would be easy! ;-)
All the best, Nick.
