Your edit to your original comment was important information I was missing - you are correct that that would probably work.

With how wlroots-rs is setup it does require the upgraded resources to not be leaked because their drop impl decrements the reference count.

Regardless, this was obviously only one part of the problem I was running into. As well, as can be seen, it's very complicated trying to ensure this is all sound and it's no longer worth the headache.
