No, that's great and even required. I was thinking of the loglevel
change, which is something you probably don't switch very often.

Heh, I wish all our users were like you :-) I noticed how awkward
it really is when explaining it to others. Many people just happen
to do the right thing if you tell them "power then AUX" but some
get it wrong and "debugging" where their timing differs from yours
can be quite interesting.

There's still a little window where changing or bouncing AUX can
cause trouble before you get there. I don't recall the exact
duration, but it might be tens of milliseconds.

Yeah, I'm hoping we can "outsource" this to the community but
perhaps a proof of concept is needed to get things going.

Oh dear ... you seem to like the tough challenges :)
