Comparing the 1/4"-20 tripod mount to the 1/8" TRRS jack isn't a great comparison. The tripod mount has been a standard for decades and decades. The phone headphone jack fractured into competing standards years ago. Works fine for listening, but once you want to use a microphone you're dealing with different pinouts for different manufacturers, balkanized auto detection and signaling, incompatible plugs sizing, groun…
It is a good comparison to make with TRS connectors, which got hit in the crossfire. It's been a standard for decades and decades. As you say, it works perfectly for listening. And for those of us that don't want remote controls or microphones on our headphones, the connector is an unfortunate casualty of "progress".
My next phone will also have a headphone socket.
