'simple' means extended one property at a time with little foresight. In
the end, 'simple' bindings are never simple. s/simple/generic/ as well.

When we first started the clock binding, we had exactly this. There's
still bindings for at least some of it. It turned out to be a bad
idea because it was difficult to get correct and complete. So this
binding is exactly what we don't want.
