I dont know if that is the intended behaviour but in the video you did a rotation on the middle of the cube ( of 720° more or less) that when u went back to rotation 0° it had some deformation applied, is that intended or a bug?

@David (Galagax), think this is due to an incremental nature of the transform tool.

What is the difference between elastic transform in this case and proportional transform in other modes? Do we need to bring a new term?

From implementation side there are some easy-to-address points. For the rest it'd be nice of UI team will make sure it fits nicely within the rest of Blender.

For context, after switching the transform tool to work on deltas, enabling the cloth deform target is trivial and it has plasticity collisions by default (see P1764).
This is the kind of functionality I'm trying to do:

Looks interesting, but the incremental nature of transform tool is what:

• Not how transform works anywhere in blender, consequentially..
• .. is what confused @David (Galagax)

It might be acceptable, but is to be done as a design decision with all the outcomes of it being clear, and have UI/UX and sculpting artists in the module agree on it.
