I kicked off a discussion 5 years ago (according to trac) and suggested the Bounded solution. I still miss these instances and find myself redefining them. It bothers me, however that the Bounded constraint is unnecessarily restrictive. We only need UpperBounded for Min and LowerBounded for Max.

Indeed. And this isn't the only place the distinction is worth making. Those two classes are in the prelude I've been developing over the past few years (for personal/internal work). One of these days I'll push it to Hackage, and maybe one day it'll make it's way into Haskell'. -- Live well, ~wren
