Sure, but what's the solution (if you're Cloudflare)? You can patent CNAME flattening, only use it defensively, and maybe you eventually go bankrupt and someone scoops it up (not great). Or you can NOT patent it...and some troll probably will, and can now use it offensively. The solution is patent reform on this kind of obvious bullshit, but that's not something Cloudflare can solve.
