I've started a little project so I have an excuse (and the ability) to play around with TMVC.

It's about creating and maintaining one ore more Warhammer (the tabletop) armies. If you want to know more about the project I'll gladly go into more detail but for my question that's not really necessary.
As far as I've come to know TMVC all custom plugins are available for the controllers only, right?
Do you plan to add some way so you can define plugins for Models? I'm thinking of some kind of caching plugin for example to reduce database traffic.
I know you can cache using Smarty but that's not really the same IMO. And it's only an example

The very existance of the "proprietary" database plugin shows that plugins for Models are useful.
