The article is interesting in that it kind of provoked thoughts out how you think the B&R list should be managed. I’m just not sure that I agree.
The minimalist approach has a problem in that it’s really only band-aiding much larger wounds and then every set with decent printings, like Karn/Forge or TC/Dig, ends up with a few bad months of Vintage followed by a restriction. This ultimately completely defeats the purpose of having an eternal format. Not only can you not really play your deck from 5+ years ago, you often can’t really even play your deck from like 3 months ago (due to frequent printing/restrictions).
I think there is probably a middle ground between your minimalist and mine/Brian’s scorch earth that was elaborated on a couple months ago that would probably be best for the community. That might mean letting go of a couple of “pillars” to give the house some more space.
The minimalist approach was never going to work if Magic just kept on living and producing 3-5 sets a year. It's the nature of a non-rotating format with a singleton list. Eventually Vintage will have infinite restricted cards given infinite new printings.
