I love GrapheneOS. The biggest downside is that Google integrity API block wireless payments in Google Pay. All Dutch banks now advertise to install Google pay for wireless payments.
I've tried asking Google to support GrapheneOS but they told me to do a feature request. Which I did and got no reply to. I've contacted the consumer market authority and made a formal complaint since Google and Apple share effectively a contactless payments duopoly and decide which OS distributions get access. Those are closed source and usually bundled with a lot of spyware. I also explained how the Google integrity API might affect banking availability in the future (and already does for some banking apps). They took it very seriously and I hope to hear from them in the future.
