Today? I have basically zero issues using GOS as my daily driver.
Tomorrow? Who knows? Just look at what happened with Revolut. They updated the app and suddenly you can no longer use it on GOS. Or the multiple times the same thing has happened with government apps that are essentially required in daily life in various countries.
Google will do basically everything they can to make Android a walled garden. They have massive incentives to keep their apps a root level part of essentially all Android devices and force as much as possible of the "necessary" (as opposed to luxury) apps into reliance on the App store.
Solve the Play Integrity issue and GrapheneOS becomes a fairly easy to recommend daily driver for basically everyone.
Until Play Integrity is resolved though, GOS isn't a suitable daily driver for the vast majority of the populace because critical apps they rely on daily may well irrevocably break at literally anytime.
It is also one of the issues stopping the development of other hardware that can run GOS and a broader market for Google free smart devices.
Bluntly, if it can't connect to the Play Store, download any apps on there the user desires, and have those apps just work then the potential market is miniscule relative to the population.
