No, this is for connecting headphones that are already paired but disconnected. For my Sonys I had to do this every time I activated them, because I use them with multiple devices, and its not guaranteed that they connect to the right one.

Some headphones support connecting two devices simultaneously, which is great... unless you have 3 devices :)

Anyways, if I was Apple, I would have added paired headphones to the speaker menu.

The W2 chip or whatever it’s called, inside the AirPods, allows it to detect the closest “known” (not “paired”) device when it’s removed from its case, and if it’s not the one that it was connected to when it last went to sleep, then the headphones will avoid automatically connecting to the device they were previously connected to on last use, instead going into an implicit “trusted pairing” mode that allows the first known device to express an audio intent to become the BT auto-pair + auto-connect device.

You can’t do this with a regular Bluetooth audio device that doesn’t have the W2 chip, because according to the Bluetooth spec, you can only be paired to one device at a time; there is no separate concept of “known” devices; devices that auto-connect stay auto-connected on sleep+wake; and devices that connect (therefore devices that auto-connect) must stop announcing themselves as available over BT discovery. (BT is essentially a protocol state machine — a device can be either idle, in pairing mode, searching for its paired device to auto-reconnect, or connected, and none of these states can overlap.)

These are all limitations of the audio device, not of the host OS. Limitations required for Bluetooth conformance! Apple can only work around these limitations by having the device and host both run a completely separate, second discovery protocol over completely separate hardware, that just forces the BT hardware into certain states as a result of its own negotiation. They can’t magically make audio devices that don’t have a W2 chip do this out-of-BT-band negotiation.
