Kind of a non-issue for me since I'm almost always using a mobile BP.
But on the rare occasions when I'm using a paper BP (flying a foreign airline, mainly) I have never shown it to anyone else other than the GA.
On Southwest, I might tell 1 other person my number (or not) but that's also a mobile BP that I don't actually show anyone.
