I get the appeal, and I get it's a PITA. But, if the referenced CloudFlare support document is to be believed, then you'll be putting yourself at additional risk by whitelisting, or otherwise "turning down" the security related settings for Tor users.
Let's pretend for the minute the support article is accurate, and let's pretend CloudFlare's security checks are useful. (I don't have any opinions/knowledge myself if there are true/false, so let's assume they are true - as most CF customers will).
Why should I turn off the security CloudFlare is providing me? The appeal doesn't give me anything I can use to justify turning this off. Given the percentage of tor users vs not-tor users, I can't really call the "it bothers Tor users" statement justification for turning this off.
I know it shouldn't be needed, I know anonymous browsing should be taken for granted, however - reality is - it's not. For an appeal like this to succeed, or even make a measurable dent, you'll need more.
I do hope you find more, anonymous browsing should be the norm, not the exception - but I don't believe this appeal will make a dent.
