The church has tended to tread very, very lightly on what they're willing to declare to be doctrine, and what they aren't, because they're aware of how bad it looks when they have to walk doctrine back. The November policy, for instance, was explicitly called out as being revelation from god (via Russel Nelson, in 2016), but the church had to walk it back in 2019 because they were hemorrhaging members and getting incredibly bad press. (Plus, the whole article of faith thing about, "we believe that men will be punished for their own sins, and not for Adam's transgression" is kind of undermined by not letting children with gay parents be baptized.)

As long as it's dogma rather than doctrine, the church has the benefits of members conforming, without the same risk of blowback. That is, if/when it's necessary to roll something back, it's much easier to say that it was never doctrine in the first place, and that the mind of god hasn't changed.
