From the comments here, many people don’t get the difference. If you’ve never flown with a kid, there is a nuance that is easy to miss.
I was going to make a comment earlier about how my kids travelled in car seats years ago before I realized you were talking about lap kids without their own seat.
Any suggestions on how I might clean up the wording? Currently I have: "In fact, one specific place where I'd like to see this thinking applied is adjacent to this rule: babywearing carriers on planes."
