I'm sure that the need is the latter.   At least for me that would be  
helpful.

Even if the faceting had a feature to still compute all the facets  
but limit the response to a given amount and provide a total (given  
the current constraints) facet values it'd at least reduce the  
communication over the wire.  I think that'd make a big difference in  
performance for one of my applications where we have an unusually  
large number of facet values.
