I'm not sure, I've never used it. But I think the issue is that the number of MCUs that support micropython is very small.
MicroPython supports[1] PIC16 and SAMD21/SAMD51, STM32, ESP8266/ESP32 and more, but it also supports Zephyr as a target, and with it the platforms Zephyr supports[2].
So yeah not everything under the sun, but certainly not what I'd consider a "very small" number of MCUs.
Of course, support level varies among the platforms, but you're not going to be doing too fancy things in MicroPython I imagine.
