the LineageOS teams refuses to incorporate patches to support MicroG as a replacement for Google Services so anyone (including me) that wants to follow that path is required to use unofficial builds.

They stopped that malpractice a while ago (last year?). Signature spoofing is now possible, so microG should work.

But they really hurt their credibility with the prior stance, and that their subreddit still has rules forbidding almost all discussions - interpreted as just closing all questions regarding blocked topics, like rooting, microG, Volte - is still a stain on an otherwise great project.
