Also, just remembered -- in French ordinals are used for abbreviations
like Mme, which has nothing to do with numbers at all.

Summary of arguments in favor of font-variant-numeric:
   * Unlike superscripts/subscripts, doesn't represent semantic meaning
     or have synthetic fallback, so avoid font-variant-position.
   * (In English) associated mainly with abbreviated forms of
     ordinal numbers, so font-variant-numeric makes sense.

Summary of arguments in favor of font-variant-position:
   * Like superscripts/subscripts, is a size/position transformation.
   * Unlike other font-variant-numeric values, isn't actually applied
     to digits, but to letters.
   * Putting 'ordinal' and 'superscript' together in one property
     helps authors notice that they are two different things,
     since they are often confused with each other.
   * Might not even be limited to numeric use cases, in which case
     putting in font-variant-numeric is inappropriate.


P.S. Tangent comments: Wikipedia has this nice image:

   * It looks like we've covered 3/4 of the possibilities. Is there
     an OpenType feature for the last one, too?

   * Are there consistent names for the different positions?
     If ordn isn't actually used only for ordinal numbers, maybe
     we should adopt a different name, even though it doesn't match
     as well to the OpenType tag?
