I recognize that some of those are features and not bugs for some users, like the "App Store madness" and the lack of a Photos app alternative, but overall those seem like huge gaps that make it a non-serious alternative.
Really I'm not sure why anyone who values convenience over security and privacy would even consider GrapheneOS. It's not made for normies. It's not advertised towards normies. It's an OS for schizos and tinkerers like me. It will never be a "serious alternative" to whatever manufacturers ship with their devices.
What really grinds my gears is people installing GrapheneOS and then loading google play services onto it. What's the point? Just stick with the stock OS. It works better and has all the features you want.
It makes a lot of sense to do that, since GrapheneOS sandboxes Google Play Services like any other app and you can revoke most of its permissions. On stock OS Play Services is privileged and has access to pretty much everything. So, using GrapheneOS with Play Services is a vast privacy/security improvement. And then we haven't even talked about rerouting location requests, etc.
Even if would use GrapheneOS and then set it up as closely as possible to Pixel OS, you still benefit from a lot of security/privacy improvements.
