It depends on what you define as a bad habit. I'd definitely discourage this 1x1 millimeter tablet area you're talking about, but area is mostly preference.
As long as you're not using a coin-sized area, or full area fullscreen on a massive tablet, you're probably good to go.
As I've heard and said before, the best tablet area is the largest one where you can comfortably reach all 4 corners of the screen.
