    possibly because of the limited depth? folding anything larger than a floating action button would require it to go higher than the maximum elevation (the surface of the display).

      Hmmm, interesting, let me crunch that thought for a moment :) Thanks!

      Pretty sure that this is exactly right. Thought I saw this in the MD spec at one point, but I think it may have been removed for conciseness.

      Here are two other ways that you can think of this distinction:

      1: Elements (folded or unfolded) always stay in their original state.

      2: Interactive elements in particular can never fold (due to the aforementioned lack of depth in the environment).

      The folding interaction and animation as used by Flipboard and Facebook Paper look pretty unnatural, as they assume a disproportionately large level of depth (~3") on relatively thin devices (less than 0.5").
