He says “no commercial interest” but honestly I bet there could be. For one thing, there is still an astounding amount of VB6 out there is real use. I know of several US law enforcement agencies with Petabytes of data stored in an evidence management system whose UI and core logic is VB6 for example.
Also, there is really nothing quite like VB6 out there today for rapid prototyping or rapid GUI desktop dev for amateur devs. It is a niche that has never really been filled.
If this can run VB6 apps cross-platform on a modern foundation, that could be huge.
[yes, I realize this is a one man hobby project with no such ambition. I am talking about potential.]
