I think you are not fully giving credit to the size of the type one community compared to other formats.
There have probably been more hours put into testing standard in the past 24 hours than have gone into vintage in the past 5 months. The vintage community is really small, maybe 10,000 players tops, probably much fewer and it tends to be older players with jobs and other commitments. Standard or modern are played by millions of people and many of them are kids or college students who can easily test 4 plus hours a day. Some of them are literally professional gamers who can test 12 hours a day leading up to big events.
To compound the huge gap in hours spent, vintage is also a much harder problem; so many more cards, so many more possible decks. The fact that we as a community haven't found a deck building solution to the current meta is only very weak evidence that it doesn't exist.
Note that I don't think that means people should do nothing and wait for a new deck to be found. At some point looking at a puzzle you have to acknowledge that if you haven't solved it yet you're probably not going to. But I also wouldn't be totally shocked if someone built something that beat current builds of mentor and shops forcing those decks to change somewhat.
