The faults you and others have pointed out seem to have more to do with
older API's like GDI, rather than a specific fault of the model per se. 
Font weight values in CSS are based on the weight values defined in

If GDI problems force vendors to ship with skewed values (e.g. 250 ==>
Thin, 275 ==> UltraLight, etc.), that's a complication but not something
that necessitates a change in the model.  Implementors will lose a
little more hair but it's not something that needs to get pushed through
to authors; specifying a thin face should result in a thin face if one
is available.

Do you have suggestions for a better model for weights?  Do you feel CSS
font weights should be any integer value between 100 and 900?  Or that
simply more weight values should be allowed, a 13-point scale instead of
a 9-point scale for example?
