Does this finally fix the shitty audio quality when using a wireless headset's microphone?

Sub 1ms latency is a big deal, currently some gamers who would otherwise want wireless devices stick to wired for the latency advantage.

I haven't tried a bluetooth device in years, is pairing still godawful? I wish they would give you the option to pair through USB. Just plug in the host and peripheral and press the pair button, and it should automatically negotiate pairing. I don't care if it requires the hassle of occasionally having to plug something in to pair the two devices as long as it works 100% reliably.

Bluetooth is horrible and can't be replaced fast enough. It's also very insecure with rumors of that being on purpose, just like many other technical implementations.

Please Bluetooth devices, give me some options on how to interact with devices I've previously paired with other than "upon spotting, immediately begin playing music"

I worked in BT almost a decade ago for 4-5 years. My first job. I had never worked close to the hardware. It was nice. Even though the work was not assembly-level close to hardware. Then the rot hit. I saw BT had been there more or less for decades and in one way or another it was going to remain there. The big bad world of backward compatibility and having to support older devices out in the wild was so crucial (as per the companies' POV and I am not judging it either way) that I realised I do not want to keep copying and pasting one line for a driver fix from one code base to 373 for different devices. Given it could have been improved with CI/CD and better source control (maybe!) but it was just not worth it.
Then the rest of the software world hit hard, and I saw, yet again, that the grass is green and that at least the world of BT had epic job safety, slow but stable growth, and best of all - no rush to fix something in the next 37 mins or millions of ad revenue will be lost.
But I see, as I had guessed, not much has changed "more or less" :)
I blame Apple as well, or both Apple and SIG for not making adoptions faster. But then Apple had nothing to worry about when it came to backward compatibility. So "Apple-rest" never really happened in a meaningful way, and whatever happened happened quite late.
(By the way there are more details on SIG portal if one is interested. Here are some https://www.bluetooth.com/bluetooth-core-6-2-feature-overvie... and https://www.bluetooth.com/blog/just-released-bluetooth-core-... and maybe follow from there)

What’s the status of audio on modern Bluetooth? The only decent mic+audio configuration I’ve ever experienced is AirPods on apple devices, anything else sounds terrible when the microphone is activated.

If this doesn't fix the damn "audio quality goes to 10kbps if you also want a mic" I'm going to electrocute the devs responsible with the voltage common BT devices running this stack require.

Any interesting changes regarding BLE Meshing?
We evaluated it BT5.x and the performance was not overly satisfying.

Bluetooth is such a shit standard. I guess we're stuck with it though.

Why does Bluetooth do that hands free profile and low bitrate on my fedora laptop, bit not on my Grapheneos phone? They're both open source, no?

BT standard wasn't even that bad, from security stand-point, the worst thing is implementation and maybe only SW implementation.
Televisions(eg.: LG) where you're unable to turn BT off. With that knowledge, you can buy cheap device which is normally used for development and analyzing of BT communication.
And with that device, you can spam any TV around you with fake BT connection requests, TV is basically unusable during this time and best thing, this cannot be blocked :D
(only way to turn BT off on LG TV is with you getting root and downloading homebrew app, which of course degrade the use of your TV remote, because it uses BT)
