Waffling?

WCAG 2.0 draft: "2.2 Use style languages, where available, to control 
layout and presentation. Where practicable, provide (or link to) multiple 
style sheets, each supporting a different output device."

I'd hate to see "until user agents" supplanted with "where available" and 
"where practicable". As my surgeon/mentor (performed eye surgery past his 
80th birthday!) says "Be Bold!"

A famous aphorism is "I'd rather beg forgiveness after than ask permission 
before". It's OK to be dogmatic and allow reasonable exceptions that 
account for practicality but we should be clear that we are 
recommending/demanding the use of styles for presentation. If we aren't 
firm about this, shame on us all.

The other guidelines/checkpoints do not contain this sort of "waffling" - 
nor should they.
