The fake library uses math/rand for random numbers generation. While this approach works fine, the Go project has since created the math/rand/v2 version of this package, which contains some changes that are incompatible with the original version. While it is not mandatory to migrate to v2, the following blog post documents why a v2 was even created in the first place and one of the reason is improved performance by using a new generator algorithm, better scalability fixing the seeding responsibility.
