I'm not sure if I fully understand the use-cases of recursive edit.
Nor am I sure if I worded this question correctly.

But every now and then when I'm doing something I'll look at the minibuffer and see that I'll be currently in a layer of recursive-edit, when I'm certain I didn't do anything explicitly to activate it.

Since this seems rather harmless, I'm wondering what the implications would be (or any problems I might run into) if I were to work in multiple layers of recursive-edit over the course of an editing session?

Obviously I would never do this, because it doesn't seem practical. But I'm wondering if any unexpected things would happen whilst editing?
