I use unmountOnBlur because my screens have a semi-transparent background (with BlurView on iOS) to allow a background video to be seen through my screen at all times. Without unmountOnBlur I can see my previous tabs through my current screen. Would this change preserve the behaviour of removing the blurred tabs from view?

@evoactivity unmountOnBlur can easily be implemented in userland:

const isFocused = useIsFocused();

if (!isFocused) {
  return null;
}
