What is the difference between hide and unmount?

I'm having a hard time understanding the conceptual difference between hide and unmount from the layout docs.

When would one use unmount over hide or unmount over hide?

:hide doesn't do any cleanup, :unomunt does cleanup.

Say you :mount a popup, then modify it's content (e.g. write something on the buffer).

If you do :hide, that modified buffer content will be preserved. If you do :show afterwards, you'll see the same content.

If you do :unmount, the buffer will be destroyed (along with other stuffs, e.g. keymaps). If you do :mount/:show afterwards, a new buffer will be created.
