I think that many traditional wet flies and soft hackles are primarily caddis imitations. It was only in the realm of the dry fly that there was any shortage of caddis imitations. The fact that caddis are less often seen drifting along for great distances on the surface probably accounts for this. G.LaFontaine also referred to the myth of the caddis as a super quick emerger that was not readily available to the trout as an emergent adult.
