This. It’s weird how a particular GrapheneOS supporter keeps arguing how awful /e/ and CalyxOS are/were, and how microG is the worst thing ever. But then offers only native Google or nothing for Play Services (sandboxed mind you). The very first fallacy you learn in Cybersecurity is that if it can’t do what someone needs, it’s not secure because it’s not viable. Having nothing for Play Services is often not an option for many people. And when Google itself is one of your threat actors, literally the world’s worst solution that provides the barest modicum of protection against Google is by definition more secure. Just allow Sandboxing MicroG as an option already for those of us with a bigger threat surface from Google than from Cellebrite-using nation-state actors.

Full disclosure: I’ve looked at using their absolutely excellent build tools to create a fork with MicroG allowed. But it turns out to be non-trivial to add the signature spoofing permission to the system and grant it to only MicroG, and conflicts with the custom Google Play config that allows Sandboxing.
