Feel free to do that, but before pushing I'd like to have Laine's
ACK since he's the one who introduced the functions in the first
place.

I think reporting the address is enough. The idea is to give the
user some information they can use to figure out which device is
misconfigured rather than just telling them there is an issue and
leaving it at that.

I also think we might be at a point where enough big changes have
been made that the best way forward is probably to post a v3 that
includes those and then use that as the basis for more fine-tuning
for minor stuff such as error messages and the like. Does that
sound reasonable?
