Yes, we should choose names that match the style of the other keywords
in CSS. No need to copy the naming style of OpenType or other font formats.

Moreover, I don't think it is a requirement that CSS supports all OT
features. A handful of the more common ones is enough. If a designer
wants a specific feature of a specific font, he can make a new font (or
a virtual font) in which that feature is turned on. That's what we have
 @font-face for.

We don't provide ways either to replace colors in a JPEG or change a
circle to a square in an SVG. The designer just makes a new image with a
new URL. That's a more flexible and modular solution.

I think we should provide keywords for small caps (already done) and
oldstyle figures, and maybe one or two more. But if a font has half a
dozen different ampersands and the designer really wants the fourth
variant, he should make a font with that glyph. (Or maybe he actually
meant to use an image?)
