Should we add fix for SF=6?

There is a PR in Adadruit_CircuitPython_RFM that fixes a known issue with Spreading Factor = 6

https://github.com/adafruit/Adafruit_CircuitPython_RFM/pull/10

Should this also be implemented here?
It will increase the size of the library and further impact the smaller M0 build (feather M0 rfm9x)?

Users who need SF=6 can use the Adafruit_CircuitPython_RFM library but that will not run on the small M0 boards.

SF=6 is not supported by the RadioHead Arduino library so without it, the adafruit_rfm9x library is still "compatible" with Radiohead ;-)

I don't know how much it will increase the library - likely a few 10s of bytes.

How you would like to proceed?

Start by reviewing PR #10 in Adafruit_CircuitPython_RFM and comparing its SF=6 fix with the Adafruit_CircuitPython_RFM9x implementation. Assess the effect on the smaller Feather M0 RFM9x build and RadioHead compatibility; done means a documented decision and, if accepted, a tested implementation.
