I don't believe for a moment that was the initial aim of systemd. They just tried to improve on a pile of hacks and by pulling on that string it sort of ends up touching (or from your perspective infecting) everything.
It vaguely reminds me of people arguing about "what color is your function". You open that portal and end up in a new universe. All or nothing.
The unix wars are long over I'm not sure what you can point to that ever was a True Unix. Nostalgia not withstanding. What well defined standard Right Way you're actually clinging to is not clear.
Whether it will end up for the best or not I don't know but the entire saga seems to be the pitfalls of endless tinkering on display rather than some unifying vision. I wish we lived in a world where systemd type efforts had clear end goals and well thought out architecture in mind when they start but open source doesn't like working this way.
It just ends up as "my favorite way of doing things is better" based on vibes. In both directions. That's the problem with "philosophies".
It may not been the initial intention, but the aim of adding a layer to the OS does lead to what is effectively a new OS. Its a bit like MacOS vs BSD, or maybe Chimera Linux (Linux kernel with BSD userland) or Debian/kFreeBSD.
The best argument I have seen for systemd is that it adds a layer that will be used and standardised across multiple distros (most effectively in a video of a talk by a FreeBSD developer). The best argument against is that it is massive and does too much.
Given android doesn't use systemd, and containers don't expose it even if the host machine uses it, systemd isn't actually that entrenched or irreversible. Containerized applications don't know or care, and neither do all the people toting around android as phones, tablets, or laptops. Unix may only be tied together as a concept at this point by a posixish libc api, and that is probably just fine.
I'm pretty sure ChromeOS is getting upstart from their Gentoo base, so what little maintenance it needs should be shared. And I do mean little maintenance; without systemd's infinite scope creep, an init system could reach "done" and coast indefinitely.
