Don't be tempted to expand what's done at the generic level.  Platforms
may need special handling at the current clock level before the parent
clock level is considered.  Also platforms may not have parents so it
becomes mere bloat.

The more complicated the generic level becomes, the more platforms won't
covert to it.
