This can also be considered a good argument to make as many of the breaking changes as possible at once. This is why I believe we should initiate polls on all imaginable initiatives, including the Pointed. My votes for Semigroup and Pointed are neutral, i.e. 0 and 0.
Concerning the discussion on Monoid's <>. Since we've stepped on a path of Prelude generalization, what about reimplementing the ++ in terms of Monoid? It's proven to be quite useful in the Snoyman's (of Yesod)
classy-prelude experiment. Just think about it: we don't lose anything, and we get the expected String-like API for working with Text, ByteString and etc, and we also free up the <> operator.
