Sorry… I can’t comment on the “Check out amazing blab blah blah” because I don’t see those. Again, all the main developers post invitation links in the threads announcing their drivers.
The wiki site you found recently shut down and there were no takers to assume management of it and pay for the hosting.
@jdroberts has a thread on alternative methods for finding drivers in the forum. https://community.smartthings.com/t/faq-using-the-quick-browse-lists-without-the-community-wiki/273601
There is also a new venture → https://smartthingsextras.com/
I pointed you to @Mariano_Colmenarejo drivers so that should get you started in your journey.
You can also post on which driver you are looking for and community members will point you in the right direction. Community members are the greatest resource on the forum
