Should we support downgrades in ManagedTopologies?

[fabriziopandini]

Detailed Description
from #4928 (comment)

In the proposal for ClusterClass and managed topologies we are introducing a constraint that prevents the Kubernetes version to be decreased.

Should we not support any kind of rollback instead? How this should work?

I wonder what kind of downgrades are supported by Kubernetes itself (minor/patch)?

I'm not sure where I picked that up, but I thought downgrading a Kubernetes minor version is not safe (or at least not without rolling back to an old etcd snapshot/backup).

Moving to Next, Downgrades requires a bigger discussion and I don't think we can tackle this in this iteration
