Nope, that's not a good enough reason, but nice try. The pseudo- 
elements define what properties are applicable to them, and for  
"first-line" it does not include "display":

The :first-line pseudo-element is similar to an inline-level element,  
but with certain restrictions. The following properties apply to  
a :first-line pseudo-element: font properties, color property,  
background properties, 'word-spacing', 'letter-spacing', 'text- 
decoration', 'vertical-align', 'text-transform', 'line-height',. UAs  
may apply other properties as well.

[the above is from http://www.w3.org/TR/CSS21/selector.html#first- 
line-pseudo ]

I would really like to see the "pseudo-elements may only be appended  
after the last simple selector" restriction lifted, as it is non- 
intuitive, and not forward thinking for future pseudo- elements that  
may need simple selectors to appear after them.
