This would lead to all kinds of interesting cases. For example, the 
computed value of font-size is not always absolute anymore. This affects 
everything else through font-based units:

foo {
     font-family: Ahem;
     font-size: 2vw;
     margin-top: 1ex;
}

The computed value of margin-top is 1.6vw, since the x-height of the 
Ahem font is 0.8em.
