I have wanted to fix this ever since we discovered it at a previous employer.

Subject: [cabf_validation] Publicly Trusted TLS certs with .arpa domains

Hello,
In reviewing the project board [1] for our group, I did some investigation into 
the "On Deck" item for validation requirements for .arpa domains [2]. It turns 
out that according to Censys, there are currently no unexpired and publicly 
trusted certificates have been issued with a .arpa domain name [3].

When the topic of prohibiting such issuance was raised several years ago, there 
was some pushback as there were several thousand valid certificates with .arpa 
domain names at the time. However, given that there is potentially no ecosystem 
impact on prohibiting the issuance of such certificates now, perhaps can we 
proceed with a short and simple ballot that establishes such a prohibition.

If others agree, I'd be willing to draft such a ballot. Or, if someone would 
like to develop the proposal, that's perfectly fine too.

Thanks,
Corey
