Nevertheless, it is a ludicrous software limitation, probably so you get a pro; I can use Airplay to connect to my TV as a 3rd monitor on 4K@60Hz just fine while the other 2 are 1080p@144Hz on my mac mini, which is basically a MBA M1 sans the Display/Webcam.The number of people who need 2 external monitors on a thin and light laptop is in the low single digits in percentage.
Even cheap windows laptops can work around the limitation by disabling the built in display in settings if you want to connect one more monitor than supported by the hardware.
