According to Stack Overflow the first could probably be resolved with version checking:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    window.setDecorFitsSystemWindows(false)
} else {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN
}

but also... is this line even needed? What does the app look like without it?

b76f05d gets rid of the first two warnings. Now the top status bar is displayed, which is nice because we had to work around the camera notch early during development. Plus: less to maintain.
