Also, lets get all our cards on the table. Front crawlstroke is redundant, because there is no back crawlstroke. You can't crawl on your back.
Perhaps not. But there is a stroke called "back crawl", if only to differentiate it from other technically-legal back strokes, such as the Red Cross elementary back stroke or Kiefer's two-armed survival back stroke (which my friend Wally does his laps with).

Are you including trudgen as a variant of crawl? :-)
