Reliance on Google for what is really an essential function for those who aren't native English speakers is problematic because it's (a) third-party (b) closed. Same reason we don't use reCaptcha.
On the other hand, do we have to really _rely_ on reCaptcha? If their servers aren't working, use the ordinary captcha. Proofread books and still not rely on any external servers.
