Does this still require you to essentially nerf application signing in order to spoof some google play crap? If so, that's really not a viable solution.
The newer version of signature spoofing patch (included in microG's LineageOS fork) allows you to control the spoofing and make sure that it's only used when necessary and permitted, so I'd say the answer is "no".
Interesting. I know the microG folks tried to upstream a patch to Cyanogenmod, which the devs shot down almost immediately.. So you're saying that the microG folks are now maintaining a fork of LineageOS? If it's not tracking VERY closely to upstream LineageOS, then it's probably not worth it.
