Ooooh, that's an interesting bug. I'm just looking into that, because I
want to make the RFC2920 variables into an acl-able variable (similar
to "authenticated = *" or "encrypted = *"), I can see where and why it
happens, but fixing it looks like it's going to be interesting.

Yeah, RFC2920 definitely agrees with you on that.
