The only time is has come up for me is in terms of a therapist reassuring me they have them so they won't intrude upon me and that they will stay back. The first one I see has said she has "excellent boundaries" in response to my questioning her about not intruding upon me, but I also know she invited another client over to her house to watch a sporting event and that she sought that client out by going to their house one time after the client's suicide threat to check up on her. So excellent may be a bit of an overstatement from that one.
