This likely will never happen as the amount of work put into those trainers is staggering. Close to 100 trainers for a single game. If you could convince the game devs to stop releasing daily updates to their games, some after 3 years of still being in early access, then they wouldn't ever reach lifetime status to begin with.
Edit: $20-25 for lifetime titles and $7 for premium titles seems fair to me.

Yes. That site was intended to allow other trainer authors to submit and sell their trainers and CHU only published some of their trainers for individual purchase back on that site.
