This function is bad fit into lens in class; but this general implementation fits well adjunctions.

Maybe it should be even a member of Representable; then we won't need Eq (Rep f) in manually written instances.

This bad idea (to have in adjunctions). The requirement of Eq (Req f) is too strong in general.
