I don't think we need the sleep scaling factor. Before we had vacuum
delay settings, it might have been useful as a means of throttling down
the impact of autovacuum, but I think the delay settings are the better
way to go.
As for the custom vacuum_delay settings, Tom Lane's commented that it
probably wasn't needed. However I and several others responded saying
that it probably would be useful for certain use cases. I'm still not
sure how compelling that case is but it seems like a simple addition.
Perhaps this is something we can add for 8.2 if people seem to want it.

I'm on the hook for this and will start working on them next week.
