To me, worrying about how text rendered with a particular SVG glyph 
composites into whereever it is being used seems out of scope for this 
specification.  Shouldn't that just be up to the particular application 
(i.e., up to the CSS/SVG specs that might use these fonts, or up to the 
PDF spec to handle if being used in a PDF document)?

I agree, it seems like it's worth looking at these use cases.
