It might well be about to become contentious :-)

Indeed, though it perhaps should .
There is something borked with the mode setting. It isn't quite the
same thing, but users of non-trivial-kins machines report that
something keeps switching them back to Joint Mode on auto/mdi
switches. I suspect that some very pedantic analysis of the mode
switching logic might be needed.

I agree, and I feel that perhaps Axis should make the flip
automatically rather than rely on your new pin being correctly
connected in HAL.
I don't think that this mode flip should travel through HAL, precisely
for the reasons you are raising.

And, again, I rather think that they should. If (and only if) the
different modes make sense as a global state. Perhaps they don't?
(I am not sure why mode-auto and mode-mdi are different, either)
