The convention history is kind of inverted.

As you probably know, all the other pr_<level>
macros other than pr_info were added some years
after pr_debug.

g'luck with that.

Renaming pr_warning to pr_warn has taken 4 years
and it's only a 2:1 ratio in favor of pr_warn and
there are _more_ uses of pr_warning today than when
pr_warn was introduced. (1006 to 773)
