This sounds odd to me in two ways:

1. it is not "the same" confusion -- it is a worse confusion, for
   several reasons:
   - the questionable Functor instance gives a cognitive dissonance for
     not transforming the entirety of the tuple (for good reasons, but still!)
   - the questionable Functor is a puzzlingly arbitrary choice among a
     N-family of options that an N-tuple provides.

2. but even if the confusion itself wasn't made worse -- its impact has
   increased, because exposure to it has increased
