"Their so-called solution" is nothing more than what has been known for at least minimum a year and was found out by some users at Tonymac. First and foremost in the distribution was Joevt who has clarified some of the work of the drivers etc..Please see their work below. It's still under development stage.

Now you can use Antelope, PreSonus, Slate Digital, Focusrite and Apogee Digital Thunderbolt and FireWire Audio Interface and NAS on Custom PC Builds and Laptops with macOS Overview It has been so long since few Audio Interface from the brands like Antelope, PreSonus, Slate Digital, Focusrite...elitemacx86.com
They have not only fixed Antelope. But other brands like PreSonus, Slate Digital, Focusrite, Apogee Digital and few NAS brands like Drobo and PROMISE.
Such a promising thing so far when everyone gave up, especially on Antelope. They have done a demonstration too.
They just try to make money with it which obviously fails because this method
A) doesn't always work and B) can't be used by everyone.
On "their" original method is not addressed due to a bug....
I formulate differently... There has never been this, they are trying to find a way but there is currently no solution or success.
They talk about slate but funny that no slate is shown in the video.
I really know only one video where the whole thing was implemented and also ran and that was from DSM2.
May he rest in peace.
