If you wanted to install something like WhatsApp or Lyft would it work?
In my personal case though, I would still not use MicroG, and would just leave the app open until I am done using it. This is easier on Android because apps are not suspended in the same manner iOS apps are.
It's important to remember this is only a concern on non-free apps. The FOSS apps have very low power background services that check for notifications without the app running.
