FWIW, it's common to drive LEDs from GPIO pins on other micros too. From a quick look at the SAMD21 datasheet for instance, GPIO pins are rated to sink up to 10mA which will make a typical indicator-type LED probably too bright for indoor applications.

My question (which you and others have answered, thanks!) was in the other direction: the Arduino ecosystem largely works for these 32-bit chips too; what benefit is there in moving to an AVR?
