Is there a demand for pre-made test cases in the software testing marketplace?

Numerous standard features, such as Login, Logout, and Forgot Password, have matured to a common level. If we could create test cases for these features in a template-like format, it could significantly streamline testing efforts for both testers and companies. Similar to selling prints on Etsy or brushes on Gumroad, this template-based approach might find a place on a dedicated platform.

I'm curious if such a service already exists on any platform and whether there is a demand for it. Your insights are appreciated!
