 It is. For exits, of course. While "443 and 6697" is not available.
 > For clients who browse the web using both 80 and 443, if they get an
 exit that only does 443, they need to get a second exit that does 80, for
 that same interaction. Suddenly they have way more exposure for that
 interaction than they needed to have.
 This is a mixed content case. That's why MCB was activated in TBB. Users
 are explicitly warned about passive/active insecure content on secure
 webpages. More exposure of the client is far less dangerous than more
 exposure of the exit to ISP and others.
 > Pointing back to #22820: the main effect of the Exit flag is to help
 with load balancing. It makes clients choose that relay less (currently
 never) for non-exit positions in their circuits. Whereas the presence or
 absence of the Exit flag *doesn't* prevent clients from building circuits
 that exit from that relay -- that choice depends on the streams that the
 client is trying to handle, and the exit policy of each relay they're
 considering.
 And you want more exits to be used for non-exit positions, don't you?
