apparently there was a period in IC development where
it made practical sense.
Aside from the AGC, I have an application note from RCA from 1967 for a small logic
family (ECCSL Emitter-Coupled Current Steered Logic) composed of just 3 IC types:
Some families of ECL were built along this line with gates with up to
6 outputs (NAND/AND and NOR/OR) that could be wire-ORed to form all
sorts of interesting functions. (e.g. Moto MC1001).
