You're confusing modes with discoverability. Force touch isn't a mode but it is invisible if you don't know it's there. Jobs wanted discoverable, modeless user interfaces where possible (and he was right). Both the watch and force touch are horrible from a discoverability point of view.

I haven't tried it but it appears that you'll now always be able to touch "too much" or too little, which sounds scary, as I'm afraid you would know that you overdid it only after the fact. I doubt the motion feedback can prevent that, but I don't exclude the possibility that they solved it to be "acceptable" enough.

My impression based on demos, without trying is, the unintutivity increased.

Have you actually used it? On the Macbook, Force Touch is totally intuitive -- it's like using a normal trackpad. It's actually quite eery. So I don't think "touching too much" is going to be an issue, any more than accidentally clicking a trackpad. It will probably be _very_ natural for things like text selection (which is a constant PITA in touch UIs).

Ditto on Force Touch for text selection. That's a huge improvement if done well.

Personally I find the iPad Pro to be intriguing because of the stylus and the keyboard, as now it might actually be more useful than a paperweight.

When something is usable, that doesn't necessarily make it useful.
