You did not deal with the most important complains that is the easy of debugging, modifying and changing stuff. It lacks a lot of this and one can question how much of an improvement ini like files are that are then interpreted in opaque ways that to provide desired features such as containerization or jailing. I personally want to usually run containers with podman, do systemd containers give me anything or is it just more cruft, same with isolation, do I really gain much from the complex namespace abstraction rather then using unshare.

Browsers as they exist today where a mistake that is clear. those other tools you mentioned might be large but they don't violate do just one thing well.

I am not even that much of a unix guy (I use emacs which the unix people like to shit on of course and does not fit with the do one thing well). But you are not providing arguments against the issues we have with systemd and have not demonstrated its value over other init 1 systems and even the harder case you seem to argue for it's applicability everwhere.
