[csswg-drafts] [css-values] cap-height unit?

== [css-values] cap-height unit? ==
I've just found out about the `ch` and `ex` units described here:
https://www.w3.org/TR/css3-values/#relative-lengths

Cap height: This is something that could become extremely useful in 
vertical rhythm projects such as 
[Sassline](https://github.com/jakegiltsoff/sassline) and 
[MegaType](https://github.com/studiothick/megatype), which go to great
 length to attempt to find this height through other means (plus a lot
 of manual config adjustment). When combined with `ex`, we also start 
to build up a very useful picture of a font's vertical metrics.  

The best measure of this is usually the height of a capital `H` in any
 font, but could likely also fall back to `I` or `X`. 

Is this something that might be considered in future?
