The alternative is to embed a definition of all the details of shaping, 
kerning, etc, etc, in the spec, yes?  And then wait for UAs to actually 
implement it all.  Assuming they want to.

Or restrict the API to font formats that don't support any of that 
stuff, of course.  But that makes it unusable for some text, of course.

A related question: what are the actual use cases for the API?  Is 
compatibility of the metrics returned with actual text rendering by the 
browser important, say?  If so, then you can't require path data 
uniformity, since browsers do not in fact render things identically.
