Just wondering if it's been discussed whether CAPTCHA module should provide a CAPTCHA field? I'm not sure what the implications are, nor whether this would be any better for admin usability.
I thought of this while building a multi-step entity form. If I use the current interface to add CAPTCHA to the form it appears on every step. If it was a field I could simply drag it to the end of the field list and use my current grouping method to limit it to the last page. I'm sure there is a simple way that I can achieve this in code, so I'm not looking for a solution, just wanting to start a discussion about CAPTCHA as a field.
