[Bug 2137443] Re: rust-coreutils /usr/bin/sha3sum conflicts with libdigest-sha3-perl

[John Chittum]

on approach, i actually think it's safer / better to move libdigest-
sha3-perl's binary and not even do a diversion

https://bugs.launchpad.net/ubuntu/+source/coreutils-
from/+bug/2146167/comments/2

unless there are a bunch of _direct_ installs of that package for just
the binary, it's usage in the distro is as a "deep" library -- it only
has one rdep, and it takes a few layers for it to spread. Usage will be
light.

I'd wager the vast majority of installs are as a library, and having it
divert the coreutils binary when it's installed that way feels bad.
