It is.

And it is also the everything but holy hell of People who want to say they are Privacy Activists without changing anything about their Behaviour and/or the Apps/glorified spying software they use every day, aka. Lobotomies, as I call them.

GrapheneOS is very good at blocking Bad stuff. But without this Bad stuff, the Neobanking/Privacy nightmares Apps wont work, As well as their McDonalds App, and other stuff like Reddit, WhatsApp, etc

And yes, someone one really complained to me that without Gservices, their Burgerking app won't work.

Now, I don't want to say that everyone has the Option to opt out of every single one of these, but if you can't, just get a second, older phone with the Spyware, and a main one.

But the least you CAN do is not complain about your Email client or Calendar working, since those all support open source protocols. And even if not, if you have the time to migrate your whole Phone to another ROM, you have the indefinite time to migrate your Email to something like Tuta or Proton, since you can just set up mail forwarding until you migrated.
