using inline style tags directly after elements can have a noticeable speedup on a pages rendering, dynamically generated pages could quite easily have well over 30 with the only downside being this silly limit.

and that isnt mentioning the boundary situations for things like web page builders with the ability to user define styles in which having a "lot" of style tags is architecturally a good idea.

I am quite tired of this "your doing it wrong" meme when its used instead of "you arent doing the same thing I am doing"
