If I use this for a while and then decide not to, what happens?

As requested in https://github.com/humanmade/amf-wordpress/issues/21 I'm asking here now.

Let's say I implement this plugin and everything goes swimmingly. Then I need to stop using it.

Is there any documentation, or is it even possible, to disable this plugin and somehow have the media keep working? Basically: if the decision is made to stop using this plugin once it's been in use for a while, is there a way to un-do what it does and preserve media availability? I assume this would involve copying media from one library to another and replacing existing with new, which sounds like a tall order.

Or is the use of this plugin a one-way street?
