I think we need to distinguish flats with no clips, flats with loose clips, and flats with thight clips. I suspect the last - toe clips done up so tight they hold the foot immobile to the pedal - have disappeared with clipless as they are clearly inferior as means of delivering that objective. But flats with loose clips largely solve the slipping in the wet problem while still allowing modest shifts in foot position (though not cycling on the arch of the foot except by turning the pedal over) - not perfect but a compromise. The pins referred to upthread may be an alternative solution.
