For my uses, what I would love is a way to have org-mode remember how
a subtree was folded so I could hide a subtree and then reopen it

I like to use hiding for context in a project, but I get by without
it.
This is similar to something that I have often wished for: some sort
of history mechanism for the expose/hide states of a buffer. The ideal
interface would simply be for "C-_" (undo) to work on the folding
views. Is this at all feasible?
Not easily. outline-mode uses overlays to hide parts of the buffer,
and overlay changes don't make it into the undo list. Text property
changes would be undoable.
I guess storing the hiding state in some way is in principle
possible but a lot of work. More-over, it would be hard to write
it in a way that it would this smoothly integrate into the normal
work flow.
