Looks great. just some minor questions.

Do you want to keep the original fn here then we can remove it entirely in next version? I guess i don't really understand the reasoning of renaming the function to a new function AND updating the old function to be an alias of this function.

I guess there's no real reason to rename this function. The original idea was to closer mimic the C library, but that doesn't make a lot of sense now.
