AirPlay in a high-density environment isn't great

The school can put them on separate networks, or they can name the devices so it's clear what room they correspond to. I'm just not seeing the problem here.
I'm assuming the school puts the devices on a network that students can't connect to, that's just a table-stakes sane thing to do.
One AirPlay solution I've seen is a pop up when you physically put your phone next to HomePod.
I really, really like connectivity between non-linked account. It's been really useful when going to those corporate "business centers" and you want to send over a doc to print or visiting friends.
I’ve noticed that it seems harder to not use airplay on the device with an iPhone. It involves a trip to the settings menu. It didn’t used too. I might have something not set right but it seems weird to me. It’s the same with my “just bluetoooth speaker as well…)
I appreciate airplay for video though.
