I strongly prefer this proposal to either of the other two, for what 
it's worth.  Is the concern that this doesn't degrade as nicely in UAs 
that don't support preload or something?  If not, what _are_ the 
arguments against this proposal?  Links to existing discussion are fine 
if this ground was already covered.
