Let's please step back,

1) I said we'd need a LANGUAGE pragma in response to hvr
2) A question was asked about enabling it by default
3) hvr said this would need a way of letting cabal know not to build it
4) I said it could be signaled with a bound on base
5) You said this assumed everyone had the latest GHC

Your response was a non sequitur. As it happens, if you have code that
hits a bug in GHC, then a pretty effective way of ensuring that
cabal-install doesn't try to build it with an older GHC is to put a
lower bound on base. I'm sorry if that is offensive.
