To me, defining a new "time of completion" for a page which can be delayed
independently of the document load event seems heavy-handed --- adding
something new for which there isn't a clear need.

The particular API above makes it easy for calls to be mismatched in subtle

That would be perfectly acceptable, although it seems a little
overcomplicated to me.
