Just keep in mind the vast majority of the traveling public is not like people on FT ;-)
I’ve found that in practice, most people just go to the lounge the airline directs them to, even when there are better options available. (A non Delta/SkyTeam example is how people keep going to the very mediocre Admirals Club at LHR T3 when there are really nice QF and CX options in the same terminal.)
