That's the wrong framing. The NOx and SOx emissions were going to have to go eventually. It's true that it might have been better to phase it out over a year or two so it was less of a shock as the hard deadline that ended up hapenning, but we couldn't keep constantly polluting forever (which is the only way to keep those aerosols in the air).

Sulphur regulations just unmasked some of the global warming that had already happened, but that masking was only ever going to be temporary in the long run.

This feels dishonest? The sulfur clouds were keeping temperatures down. Largely in ways that were not really related to green house gasses. Exposing the ocean to more sun increases temperatures of the ocean. Likely influences currents, as well. In ways independent of heat we are trapping in the atmosphere.

Should we have stopped the sulfur? Agreed that that answer is almost certainly still yes. Questions that this leads to are cleaner artificial clouds. Not to control weather, per se. Rather, to reduce ocean heating.
