By now it has actually been almost two and a half years.

While I'm not looking to turn this into an off-platform meta discussion, pretty much all of those rules have their very good reasons to be there.
As an example, you would be surprised how many people install a Magisk module to strip away LineageOS-specific build version properties, and then end up in our support platforms asking why the Updater can't search for new updates (of course while not mentioning that they have modified their system).
microG I don't even see listed as a part of any rule anymore, it was removed when upstream support for microG was merged.
