If I install reCAPTCHA and set it to be used by a form but I do not configure reCAPTCHA, any page which should contain the reCAPTCHA is blank except for this message:

To use reCAPTCHA you must get an API key from https://www.google.com/recaptcha/admin/create

This has the potential to completely break a web site. If reCAPTCHA is not configured, Drupal should behave as if there is no CAPTCHA configured or perhaps fall-back to a default CAPTCHA.

(I wonder what happens if reCAPTCHA is properly configured, but the reCAPTCHA servers go down or are inaccessible. Does that also trigger a similar problem?)

The reCAPTCHA module calls die() when not configured. The attached patch causes it to instead display a message and always behave as if the CAPTCHA was valid. In other words, having reCAPTCHA unconfigured will not break your site.

Going through the code some more, I have come up with a much better solution. This one only changes recaptcha.module and causes CAPTCHA to fallback to the built-in math CAPTCHA when reCAPTCHA is not configured.

I must be having a slow day. Here is a simpler, better patch that implements the fallback to math.
