This is sounding like a completely runaway spec on what should be a
simple feature.

If you want something in core which will be useful to a lot of our
users, it needs to be simple and flexible. Not ornate with lots of
dependancies. The first version of it should be as simple and minimalist
as possible.

Personally, I would prefer a tool which just made it simpler to build my
own triggers, and made it automatic for the history table to track
changes in the live table. I think anything we build which controls
what goes into the history table, etc., will only narrow the user base.
