Remind me, are the certs being described below intended to be DV, OV or EV? Or all of the above?

Is there any browser beyond Chrome that does this? That is, prohibit CAs from issuing from internal names? That is, your wording suggests the only possible way to get .onion names is via an internal / non-public CA, but this isn't entirely true, and if a public CA (such as Digicert) issues for .onion, they won't get an error (... except in Chrome, for the reason being that we prohibit public CAs from issuing to non-IANA assigned domains ahead of the BR deprecation)

That said, if this is just the introduction to the ballot, and not part of the normative text, then I think these objections can be noted but may not require any textual change. We'll just point to this thread if someone says silence was assent and move on :)

Our support to co-endorse this ballot still stands. Thanks for the added details.
