another impl (not an issue, just a pointer) #1

FYI, you may be interested in https://github.com/dhalbert/CircuitPython_LCD, for char LCDs, with the interface factored out. Currently the only interface I provide is for PCF8574 backpacks (not compatible with Adafruit backpack). I did some things to reduce RAM usage as well (const(), underscored constant names, etc.)

Thanks for linking your implementation! (it's cool to see other's implementations). I'll also look into using these methods for reducing RAM usage (without a .mpy, the .py is too large to fit on boards, reduced RAM would help tremendously)

http://circuitpython.readthedocs.io/en/latest/docs/reference/constrained.html#execution-phase talks about const(), etc.. And see other stuff on that page as well.
