I am sure that it was already argued at great length, but I think it is
wrong to start the declaration with "deriving." I believe that "derive
instance" fits much better into the language. I understand the desire to
avoid adding new keywords but I think that something along the lines of what
was done for "for" could be done here for "derive."
