"These upgrades are eligible on all paid fares flown in the mainland U.S., Alaska, Canada, Mexico, Caribbean and Central America, and select flights in Hawaii and Asia/Oceania."
Which is IIRC how UA CR1s worked all along (maybe with the exception of Asia/Oceania).
I've used my UA CR1s mostly to upgrade travel companions who'd otherwise not get an upgrade, on the occasional transcon (don't fly many) and on trips to/from Hawaii where I wanted to guarantee the upgrade and not risk to upgrade lottery. The advantage of (UA) CR1s over mileage upgrades (especially on the UA Hawaii routes) is that there is no copay.
