Hi there g2oe thanks for joining our community,
Most of those are either outdated or require services like Xposed, Magisk or MicroG. GrapheneOS does not support unifiedNLP when we have the OS redirect for location to use GNSS as well as the option to use sandboxed Play Services network location services, both of which maintain the security model.
We aren't going to add support for an app ie MicroG which would undermine the security model by bypassing the signature enforcement for location providers in order to enable this. Network location is hard to reasonably implement in a private, secure and sustainable manner which is resistant to abuse.
