“Just” putting it into writing

Today’s WSJ: “Top U.S. policy makers emerged from hours of tense negotiations with a clear message just after midnight Sunday morning: A deal to bailout U.S. financial markets has been agreed on and all that remains to be done is to commit the legislation to paper.”

“All that remains is putting it in writing?” Am I the only person who finds that “agreements in principle” that take 20 minutes to nail down verbally can take months to spell out in writing, once the parties start digging into the nuances and granularities in the vague words that created the initial bridge of agreement?
