I'm tempted to just say "no there wasn't." There were good designs during times of social change. Feels that this is a general "rising tide lifts all boats" situation, though. Probably more accurate to say survivor bias.
That is, I find it hard to believe that the "designs" truly facilitated these changes, so much as they helped what was already moving. Think of it as the coefficient of friction for moving bodies. The designs and such are enough to overcome the kinetic values, but not static ones.
