:While it is true that "the lead paragraph is supposed to summarize the entire article", consider that it is not necessary that the lead paragraph be written only after the article is "finished".  Of course, on Wikipedia, an article can never be considered "finished" and therefore the lead may have to change to accommodate subsequent later changes. 
 :However, we can also take the approach that a well-written lead can drive the writing and refinement of the article.  That is to say, we could work on figuring out what we want to say, write the lead in a way that says it succinctly and concisely and then write the article to support what we've written in the lead.  This is the approach that I recommend we use.  It would help to prevent the article from becoming a WP:COATRACK.  Every new addition to the article should be considered in the context of the question "How does this information help support what is being asserted in the lead?" 

 :NB: I am NOT saying that the current version of the lead is perfect and untouchable.  I'm just saying that the lead should drive the article writing rather than being slave to whatever stuff editors feel they want to stuff in the article.  We should be willing to say "Nah, we really don't need that little tidbit of info in the article." and then revert it back out.
