That means you'd distinguish RE (replacement exists) vs DN (dropped as
non-ideal) categories?

I could subscribe to that if there weren't so many other places to
evaluate:
  $ git grep -i "pr_warn.*deprec" torvalds/master --  | wc -l
  62
  $ git grep -i "pr_info.*deprec" torvalds/master --  | wc -l
  2

So is the disctinction worth the hassle?
