Even people disagree with snap I look forward to it for this specific use case. I want parts of my system to be stable and LTS and others to be pulling the latest features. On top of this a way to rollback to whichever version in a safe and reproducible manner. Rolling release is nice but sometimes it creates real headaches.
This could be a good use case for snap, but preventing users from choosing native versions of applications and installing firefox as a snap by default made me exiled me from Kubuntu, at least for now.
