I think using Bifunctor.first and Bifunctor.second is as much an abuse as using Arrow.first and Arrow.second. When using Arrow you specialize the arrow type to (->), but when using Bifunctor you specialize the bifunctor type to (,).

I actually use my own specialised mapFst and mapSnd functions from utility-ht. I also found that I sometimes need strict versions of these functions in order to prevent space leaks.
