This misses the point. What’s nice is not that it’s just me, but that it’s everyone.

Host a “phones off” party, go to a sauna, go for a hike with friends with self control etc., but please don’t hold me hostage (connectivity wise) in a cramped metal tube for your sense of nostalgia.

Planes are just about the least pleasant space to experience involuntary offline-ness. (That said, people scrolling reels with the speaker on (or the display at brightness levels making me consider sunscreen) should immediately go on the no-fly list.)
