What about the time it cost you to search the internet, read the docs, and use the one from std? How many seconds does each variant take (with hot/cold memory cache?)
And the behavior could also be worse, there is no guarantee of perfection.
The last argument is too generic to offer any guidance. Why is it better for this function be duplicated?? Should it not be part of std to avoid uniqueness?

Duplicate code across the ecosystem is fine. Not every function must be unique for an entire programming language.
