I would prefer that the Ord constraint be retained in the type signature, even if not used in the implementation.
Just for the record: You'll have to actively suppress the resulting warning if the Ord dictionary is not used by the implementation, as -Wredundant-constraints is part of -Wall starting with GHC 8.0
It seems to have changed: https://ghc.haskell.org/trac/ghc/ticket/10635#comment:7 But I had those cases in mind when I asked for removing -Wredundant-constraints from -Wall.
