One thing that's not entirely clear to me is why the private communication exception is needed, given the generator exception. It seems to me that mail clients producing HTML should include the generator meta tag. This seems simpler than relying on a manual setting in the conformance checker.

It seems the only additional case covered by the private communication exception is hand-authored HTML sent as email. While I won't claim this never happens, I would guess it is extremely rare, and perhaps such a narrow use case does not need special handling. (There is also the possibility of non-email hand-authored HTML documents being exchanged with a known fixed audience, but this too seems like a very rare scenario.)

On the other hand, Laura's change proposal opposes the generator exception as well, so I am not sure this line of reasoning gets us anywhere.

Regards,
Maciej
