The vast majority of doctors support increasing the number of doctors. Most doctors are not members of the AMA and many disagree with their positions on many subjects. The main issue with the shortage is the lack of funding for residencies that is mostly paid for by Medicare and grants. Medical schools don't want to increase the number of students if they won't have slots to finish their training to become doctors. The limits you're talking about are comparatively minor issues as the limits imposed on MDs have led to more DOs. And what nobody wants to talk about are the thousands of slots that go to international medical students, the majority of which do not stay after training.
They currently have a senate bill to increase funding and incentivize the most needed specialties (GP and psych). We'll see how that goes. At this point, it feels like interest in being a doctor has diminished - there's too much training, many specialties don't pay well enough to justify the delayed earnings and costs, the hours can be miserable, and it's a nightmare to deal with all the regulations and legal aspects.

No, that’s the proximate issue. The main issue is the requirement of residencies for all doctors in the first place. In particular, I’m referring to doctors from other countries who may have years or even decades of experience practicing medicine being required to compete for residency spots. These doctors infamously end up driving for Uber instead of practicing medicine.
