Couldn't we do it using GHC's default implementations based on
signatures features, so we don't have to expose any new things in the
API?
We used that in unordered-containers like so:
#ifdef GENERICS
default parseRecord :: (Generic a, GFromRecord (Rep a)) => Record
-> Parser a
parseRecord r = to <$> gparseRecord r
#endif
