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

I believe this has already been fixed by LE audio.

But support (on both ends) is quite rare, experimental, and needs to be explicitly enabled.

It's been difficult for me to find headphones with LE support. And also I've seen some of them announced support, just to remove it later because the firmware was behaving so bad.

Haven't checked in a while, so I don't know if is there something reasonable now that doesn't cost like $500 or so.

Classic and LE are completely different protocols, from physical layer and up. It must be that it doesn't make a lot of sense for manufacturers to invest substantial effort in it.

Which makes sense when you know it started life[1] as a separate protocol called Wibree by Nokia, which was specifically designed[2] to be usable by Bluetooth RF gear:

A major tenet of their design was that “it can be deployed with minor effort into devices already having Bluetooth, e.g. cellphones” with the added requirement that a “common RF section with Bluetooth must be possible”.
