We've discussed this for a while now, but it's possible now this the other work Carlos is doing with settings.

I've got a WIP branch here: dev/migrie/f/settings-getters-only, with only a few errors.

I think for each of these, the TermControl is going to need to cache a local copy of the value, to represent it's actual runtime value, rather than use the IControlSettings as a buffer.

I'm filing this so someone else can pick that up where I left off.
