Just as incidental information
For other CustomROMs that supported signature spoofing, for example ArrowOS and Havoc-OS, I use the Minimal microG NoGoolag Edition.
“The NoGoolag edition is completley free of any Google or proprietary components other then Droidguard.”, promises r/MicroG.
Minimal microG uses official microG APKs so it can be updated from the microG F-droid repo. MinMicroG by MOVZX and FatherJony and FriendlyNeighborhoodShane.
