I'm definitely not 100% sure about that though, so someone please correct me if not.
- The pairing process is kinda awkward, you need to split screen Termux and the Wireless debugging submenu, if you change windows the pairing IP and code are changed.
- The pair survives a reboot and WiFi change. You can disable the 7day revocation, so the pairing process is a one time thing.
- After a pair you still need to connect (adb connect localhost:port) and the port changes after a WiFi change or disconnect. I searched for solutions and apparently it's simple as running nmap twice¹
- It obviously doesn't work without a WiFi connection (unless is there some dark magic to connect your phone to its own hotspot).
So a wrapper seems viable if you are ok only installing apps on trusted networks.

EDIT: Even more googling, the whole setup already exists in Obtainium (i.e. F-Droid but with Github Releases) apparently so apps show up as being installed via Play Store and subsequently be usable in Android Auto⁵.
So hypothetically you can install stuff day one on a stock phone after this atrocity is turned on.

thank you for the testing and details!
