... which then means it can't dock

Ok, maybe I was a bit hasty here... is this a mechanism to save monopropellant? Will keep testing

No, definitely broken. RCS is off and things are drifting away from one another.

Yes, the idea is to save fuel, but it has problems, as you've noticed. If your target-relative velocity is below a certain threshold (0.25 m/s by default), the docking AP will stop using RCS altogether. This threshold can be configured by adding "Thrust > Conserve RCS fuel threshold" to a custom window.

The default conserve threshold was too high, it's set to 0.05 m/s in 2.0.7. If you keep your settings, it may still use the old 0.25 value, so change it manually to around 0.05 to keep everything working well.
