I’ve played in a few rinks with this. Actually, Mississauga Ice Dogs has this when Don Cherry owned and coached the team, he is a big believer in 3 doors if I remember correctly
"Thank God theres still a sport for middle sized white boys"
There are a couple NHL rinks that have this where the tunnel is connected to the bench. Usually they have a door right at the tunnel exit, then one on the blue line and one in the neutral zone.
