There are a lot less GPL projects in your system than you might think. Your core system is already filled with liberally licensed libraries and programs. Case in point, since you talked about rust rewrites, original sudo is not GPL software.

If you're posting from Desktop Linux, your comment utilized at least 10 liberally licensed libraries. And that's before it got into the wire. GPL packages are a MINORITY, not a majority with exceptions.
