Hay Michael,
Have one idea, don't know if it is good but i''ll share it.
So for example we have some solid/surface that we wan trim etc..
So if there will be a function that unwrap surface to make it planar. When it is easy to make some changes on this surface trims etc.. And then warp back. Or have warped and unwrapped objects at the same time to see changes we made on unwrapped.
Just Like UV works)
