I've found that I typically don't need to know how it works if my use case is common and the library is well documented, but when either of those doesn't hold it can be very helpful to read through the implementation in the source to understand how best to implement. But I think the black box would be less of an issue when interfacing with documented third party libraries, than with internally developed services and libraries, particularly in smaller orgs. Team A 'generated' Service A and Team B needs to integrate it in their 'generated' Service B, it seems that could get messy and would be tough to test or troubleshoot. Possibly an additional AI tool specifically for compatibility and integration could solve that problem.
