You don't even have to go that far, `base64` is a coreutil (https://github.com/coreutils/coreutils/blob/ebfd80083b4fe4ae...).

The point of ut is not to replace or invent new tooling. It is meant to be a set of tools that are simple, self exploratory and work out of the box with sane defaults. So, essentially, something that you don't have to remember syntax for or go through help/man pages everytime you want to use it.

uutils/coreutils has a `base64` in Rust which just gained better performance due to the base64-simd crate for SIMD: https://github.com/uutils/coreutils/pull/8578

Note that uutils does not work if the file does not fit into memory.

With GNU coreutils:

   $ base64 /dev/zero | head -c 1 | wc -c
   1

With uutils doing the same would exhaust your systems memory until either it freezes or oomd kills the process.
