Possibly we want to refer users to the note for 2.1 on t he impact of changing this for downgrades?

What do you mean by this? As I copied the 2.1 instructions, I am not sure what information is missing?

Once you change the inter.broker.protocol.version to the latest, downgrades are generally not supported. There is a note below for 2.1. See line 75.

On second thought, the next entry is already clear. Maybe it's fine. I guess the question is whether we should make this the official rule or if it was an exception for 2.1.

This is not quite right. The change was in 2.1.x. I would suggest this:
If you are upgrading from a version prior to 2.1.x, please see the note below about the change to the schema used to store consumer offsets. Once you have changed the inter.broker.protocol.version to the latest version, it will not be possible to downgrade to a version prior to 2.1.
