Yes they were correct at the time the BAR was located at 0x100a0000 but.
But still I suspect the end-user most probably will not be able to
understand this and will interpret it as an error and report a bug;
whereas it works as before. So to me we should rather use a trace-event
for debug purpose until we find a way to output a usable hint for the
end-user.
Thanks
