Truth is R-22 did not pose a threat to ozone depletion.
No matter the solution the insane left is never satisfied.
Every 10 or 15 years they phase out a refrigerant and phase in a new one that is supposed to help the environment. It requires a brand new platform of course, and they just did it again about 3 or 4 years ago! Its like the air conditioning lobby is creating a business cycle for themselves. This seems odd because its too early after they just did it recently.
