If for instance wordpress.com starts using your method, in 2 hours spammer would get their botnet updated and your blog flooded 2) it doesn't protect against pin-pointed attacks. Captchas are not used only in in blogs but a in a wider range of services. If yyou're running a site where captchas helps you against frauds, your method will be broken again in a few hours. Ok, in this last case you should implement an anti-bruteforce method in the backend as well and do not rely only on captchas. I found 2 problems with your approach, even if I’m a KISS fan:

For one, there are some programs such as Norton Internet Security that "tinker" with the headers and may cause issues. Another is the use of translatiion sites such as translate.google.com which seem to blank certain header fields. Although the majority of visitors to a site will be okay, it never hurts to keep these type of issues in mind. This is a great idea but be aware of a few caveats.

Crawlers don't submit new content, they just index what's already there. Yeah, but as long as you only check it on submit it doesn’t matter.
