My issue isn't even that someone tries to replace sudo. That may or may not be a completely fine thing to do, depending on the state of sudo and what improvements can be made. But what makes me really upset is this completely unexplainable need to make everything part of one particular init system. There is absolutely no reason to tie your new sudo replacement to systemd. Absolutely none.
This is a completely insane way to develop software, instead of creating a new piece of software in a separate project they will force all their projects simultaneously onto all their users for absolutely no reason.
I am very glad to have jumped ship from systemd. It is particularly bad software created by a team of people who engage in very bad practices and a totally unhealthy view of software in general.
