I really do wish they would have just said, "we're banning all input broadcasting" as opposed to their current wording about software. Then they could have followed that up with a policy change saying that 1 keystroke can only equal 1 event on only 1 client. I wouldn't have wanted to hear that answer personally, but at least that would be a clearly stated policy with some more detailed understanding the community could get behind - it would give us a good framework to evaluate new ideas against.

As it is right now your minefield analogy seems pretty valid. But I haven't gotten any warnings against my account yet, so this seems like as good a chance as I'll ever have to try to tip toe across the minefield to see what I figure out. Even if all that does is to better define where exactly the mines are so we all no not to do that again, that seems like a worthwhile test.
