Not sure if sarcasm. In fact the whole point of Drawdown is to enumerate all the possible fruit, both high and low hanging, and come up with numbers justifying their picking in parallel. So yeah, refrigerant management is part of the solution, and you can check their numbers for how much it would save and how much it would cost, and that is done deliberately to avoid nonsense like "why are you bothering with air conditioners?!".

In contrast, the upthread comment seemed to be arguing that a blanket bill trying to establish a regulation framework for climate change is insincere because of minutiae about NYC's mismanaged transportation infrastructure.

Going back to your snark: it's the equivalent of "Throw the whole Drawdown plan in the trash because China has too many air conditioners." See the problem with that logic?
