I mean if one chose rolling, I think that after an update you could not downgrade to stable, or if you took cooker you would not go back to rolling, because that would harm you system, did I get this right?
Yes, you can switch to a different older Update Channel but only for a few time when the 2 branches get sync-ed such as at time of copy cooker to rolling (usually new installation images releases or major upgrades), or rolling to rock (stable point releases published).
