is this going to be a flag or a new value for ds_probing_mode? Not clear
for me yet what you thought of.

I was thinking of a new flag, but it might be for "skip-probing", if
that makes it easier to keep it compatible with current values --
haven't really analyzed the impact and which type
(do-probing/skip-probing) is better.
