this sounds dubious if one has, say, a web browser installed or other consumer-type software. you almost surely want the latest security updates (which are for better or worse often packaged alongside cosmetic or other performance updates) for a piece of software like this.
for this reason i've moved to a releaseless distro. the idea that i can't get the latest firefox without upgrading my "operating system" version to a new release seems harmful for most types of software:
- imagine updating an app required you to upgrade your iOS/android version
- imagine updating a plugin requires updating your browser
etc. it's anti-modular and so i can't support it.
