Are you sure you want to do this? You are right that it better describes the action that these probe points signify. But since previous versions of this patch have been used and applied people might be depending on the old names. It is not a very big issue, we can always write a tapset to translate the old to new names. But it is an interface break for anybody who might already have scripts around.
