Ok, so the reason I said bad is because this happens to me. I’m playing music on my laptop. I go to the bathroom. Maybe an auto-playing video with sound pops up on my iPhone. The headphones switch to my phone. Now I’m back at my laptop and have to manually reconnect the headphones.

Perhaps this is what people want, but in my cases it’s two tech annoyances (auto play video and fumbling with the Bluetooth menu).
