I don't see how is this supposed to help (and I don't think most new
users would want to do this; I certainly wouldn't).
Not to say that it would be a good idea, but Google does it already and
phone verification is probably less painful than our CAPTCHAs are to
non-English users (

In general, as far as we know captchas are currently not stopping
spammers at all, while effectively stopping many legitimate (less
motivated and experienced) users.
