So ORPort 0.0.0.0:9001 would bind to all IPv4 and IPv6 available addresses on a server?

I'd love that too -- but the thing I am thinking now is how to address the temporary addresses that are used in operating systems (in some my default, in some not by default)? Those addresses change over time randomly, and maybe more often than a relay would find useful. Is there a flag or something that can make an application tell the difference between a temporary IPv6 address and a static one, for example?
