Well, I do.

I don't agree. Further, you haven't proven that the case in question here
is even relevant to 1 author out of 100. You are asking me and other
readers to simply accept your assertion on faith that this is a relevant
hurdle for authors and that defining two ways of doing two things makes
life substantially easier for authors, and that this increase in ease
overcomes the increase in pain on the part of implementers, tool authors,
test writers, spec writers, etc. Feel free to back up your claim with
numbers and perhaps I'll reconsider.

It (perl entropy) is a metaphor for specifying a different way
(syntactically) do the same thing (in this case access font face
descriptors) every time you do it. You are suggesting two different
interfaces for accessing font face descriptors when one will do. I don't
care if it is the existing CSSStyleDeclaration interface or something new
we choose, but I don't want to see two interfaces populated with the same
or very similar members.
