I think this is basically what I was thinking of, yes. One thing we'll
need to do is work out how to handle systems that need some explicit
action to start clocks for the bus clock, though they were never very
common and it's entirely possible nobody cares any more so perhaps we
just punt and see if anyone notices for now.

Why "digital"?
