I agree to leave it as it is.  The number of Xplained Mini users
with UPDI devices is by now probably neglicible, and once their
firmware is upgraded, nobody would notice anymore.

As a stopgap measure, maybe ignore the failure status in these
commands if -F is given?  This option is already used to skip a number
of consistency/plausibility checks otherwise, and "just proceed".
