Hey, I noticed that coneOpEquiv is essentially the same as (the dual of) coconeEquivalenceOpConeOp. Do we really need both? And can the names be made more similar?

Yes we need both because F.op.op is sadly not def-eq to F :) I agree that the names should be more similar and the statements aligned (adapting the style of coneOpEquiv).
