Isn't the whole point of the zpool upgrade process to allow users to

In other words shouldn't any change that eliminates going back to an

Yes, that is exactly the case.
Unfortunately, builds prior to 35 had some latent bugs which made
implementation of 'zpool upgrade' nontrivial. Thus we issued this
one-time "do not downgrade" message and promptly implemented 'zpool
upgrade'.
Ah. Thanks. It was the one-time nature of this change that I wasn't
sure about.
