Gaming headset 3.5mm TRS mic plug pinout

It seems many PC gaming wired analog headsets have two separate 3.5mm "TRS" (3-conductor Tip, Ring, Sleeve) phono plugs:
- One for stereo audio output from the PC to the headphones.
- One for microphone audio input from to the PC.
What is the typical pinout for the TRS mic plug?
The reason for my confusion is I would expect the headsets to just have a single mic, so it seems like this should be a mono TS connector (just "tip = signal" and "shaft = shield/ground"), but instead it's a TRS connector, so I'm wondering what the extra conductor is for. Do they just do the one mic's signal twice as if it was stereo? Or do gaming headsets tend to have stereo mics even though the mics can't be placed well for proper stereo separation? Or is the extra conductor for a voltage bias to provide power so the headset can use a condenser mic instead of a dynamic mic? Or to power a preamp so the output comes out at line level instead of mic level?

According to the Intel/Microsoft PC 2001 System Design Guides, Chapter 11 - Audio, requirement AUD-0331, the pink mic-in jack is wired this way:
- Tip = mic signal
- Ring = +5V bias
- Shaft = shield/ground
So a typical gaming headset's pink mic plug must be wired accordingly.

This article is mostly about powering a PC mic from the "phantom power" that's available on pro XLR jacks. However, it does give background on the PC mic pinout and confirms this answer. epanorama.net/newepa/2014/06/30/…
