Ok, yes, I wasn't aware of the history, I use whatever my distribution uses as default, and been doing that for decades now, as that tends to be less hassle, so been using systemd for a while because of that.

With this new knowledge about the history, I still feel the same as the original question. AFAIK, no one is forcing people/distributions to adopt systemd. It might be easier, and most takes the easiest route, but that's OK, right? That doesn't mean that you cannot make another choice, maybe involving more work, but you can still make that choice, unless again I miss something obvious here.
