Interesting. Thanks for pointing that out to me. However, it says not to 
combine with DNSSEC in bold letters with an exclamation mark, so that means I 
can't use it.

Out of curiosity, 1) Why can't it be combined with DNSSEC? Is it just not 
complete yet, and DNAME+DNSSEC support is coming later? Or is it something 
else? 2) Why does this approximately double query load?

Indeed, you're right. I can't find any clients that support CAA. For that 
matter, it appears that none of the browsers support TLSA/DANE, either. That's 
a bummer. I was looking forward to rolling that out, but it won't really make a 
difference.
