The only limits it has or enforces are the structural and architectural
ones dictated by the layout.

I think growing is out of the question. It has a fixed maximum size
already. As for shrinking, there's probably a use case for when
something is large, then shrinks back down. But, I think I'd want to
see a user for it, otherwise I'm just guessing at it too much.
