The draft of the 3 release policy has a very strict requirement for warnings, "without causing warnings even when compiled with -Wall". This causes breaking changes to be spread out over a number of years because of deprecation warnings.
I propose that "-Wall" in this sentence be replaced with "-Wall -Wno-compat". As we are addressing an audience who wish to suppress a specific category of warnings, it seems reasonable to ask that they make this explicit.
my impression was that "-Wall" would not imply "-Wno-compat", bringing the policy in line with what you intend it to do. And I agree that this is the sensible policy. If that’s not the case, we should consider if it maybe should be the case :-)
(I would also prefer for -Wcompat to be on by default, but that would be another discussion, if and only if this proposal is accepted.)
Indeed a different, but worthwhile discussion. As always, I’m far from having a fixed opinion, but want to note that a lot of code is _not_ library code, and compatibility with one GHC version at a time is all that matters, and (momentarily) irrelevant warnings are annoying. That’s a point in favor of _not_ having it on by default.
