It supports more devices than GrapheneOS i.e. nonpixels. That is where I would totally use it.

It’s very loosely based on LineageOS, which is where all it’s device support comes from.

Would love to use UnifiedNLP

Unfortunately, UnifiedNLP is not supported. Quoting from their FAQ Page: Network (cell tower, Wi-Fi, Bluetooth beacon) based location providers such as Google Play Services, Qualcomm IZat, and microG/UnifiedNlp are not supported.

Sorry to break the news to you :(
