Personally as user of libraries I have no problem with warnings. Because
- I can't improve it
- I got it only once when install library
I just care about warnings in my projects and that is not so hard.
So I want to say that it is not a big deal. Perhaps warning's levels are
good but simplicity is more important for me.

A "3 release policy" has been recently mentioned several times, whereby it should always be possible to write code that compiles with the last three releases of GHC, without generating any -Wall warnings.
The no warning requirement seems excessively harsh. Will early warnings of impending breakage really cause so much trouble that accepted proposals have to be dragged out over several years to avoid them? If so, would a flag to suppress the warnings suffice?
I should note that GHC has traditionally had no qualms about introducing new warnings, on by default.
