Adafruit_Blinka: Problem with spi and MicroPython

I ran into an issue trying to use Blinka under Micropython on a Raspberry Pi Pico. I was trying to see if I could use an “airlift” with the esp32spi library. The first problem had simple “workaround”: The esp32spi library uses time.monotonic() but time.monotonic() is not provided by the micropython time module… It looks like a simple fix is to just use time.time() use MP but it does mean a lot of CP code won’t work without modification… I did make that change and ran into some more significant issues that may indicate bigger problems, but I wanted to point out the time.monotonic issue to see if I was missing some thing simple to get around it.

The second issue may be more significant: after replacing the time.monotonic() called with time.time() in adafruit_esp32spi.py I ran into this

Any suggestions on how to proceed?
