Yes, it did get overlooked. The wording about accuracy on initial zoom
level from the message you cite did get added, but the change from
device pixel to px unit was overlooked. Thanks to you both for catching
this, it has now been changed in the spec to "px unit" as previously
promised.

Please let us know within two weeks if this is not satisfactory.
