I remember Fedora proposed changed the /usr/bin/python symlink to point
to python3 (breaking _everything_). I don't remember if they ever
actually went through it:

Yeah they're the same file. Numato is the manufacturer, mimas_v2 is the
board.

The protocol is more or less trivial, it's a series of 27 byte packets
with some minor setup stuff. Porting it to C might actually be easier
than porting to python 2. But with the current tool the actual flashing
part takes 10x longer than even cursoring up and hitting enter 20 times.
(It fails reasonably fast when it fails.)

So I haven't bothered yet. It's waaaaay down my todo list. If somebody
else wants to... :)
