Doing a patch like this won't affect userland, but also I would wish we didn't need to patch users either. I will talk to Evan to see how we could move forward for that PR. In the meanwhile, I see this PR does not include logic changes to adapt that feature, nor tests. You can help to do some testing so then we have a clear image of how many issues we could solve by introducing it.

Marking as a draft for now.
