Eh, It can be good or bad. While generics (in C#) can make your code easier to use correctly, by making sure that everything is of the right type, and can give you a nice perf boost when using generic specialization with structs, they also have a tendency of infecting every bit of code they affect with more generics. For example if a function is generic over T, where T is parameter X constrained to be `ISomething`, all the function that it calls with X should use constrained generics as well, this can easily lead to the explosion of generic functions in your codebase. Many times, instead of making a function generic over T it's easier to make parameter X just be interface `ISomething` and be done with it.
