1 - makes sense. So, just delete it then? Sounds like it can't be used with GrapheneOS.
2 - good question. When I first set the phone up (including play services) I got a prompt to install various Pixel apps (I'm guessing it was play store recognizing the Pixel device). I allowed so I could check them out. I'm gonna guess it was then, though I don't think it was listed.
3 - due to increased attack surface? Are there situations that an app can use them without user intervention? I use it to run scrcpy when working on the office. Thanks for the tip!
