Old does not mean bad but Linux chooses that path as it moves further away from UNIX and being a Unix-like system in its pursuit to be Windows.
It doesn't automatically mean "good" either.
> "in its pursuit to be Windows"
Would you please elaborate?
Systemd does a similar thing.
Now, traditional BSD inetd had discard, chargen, echo, ... protocol support, which means that it was actually more integrated that systemd.
Well, people are still free to maintain and improve those older tools and bring them up to par with newer standards, if they want to.
Others would argue it's time to start phasing out code and so-called "standards" we've had since the early 90s in spirit of refactoring various elements in the ecosystem. As with most such efforts - lots of code will be thrown away, some of it will be re-used and re-purposed. I'd argue that in the long run - it's probably a necessary intervention.
So the notional idea of 'refactoring' being better -- yes! But with the constraint being that the people doing the refactoring have to be at least as wise, tasteful, mature, sensible, and thoughtful as the people who came before.
When choosing platforms, how communities weigh this balance is a very important consideration. You want to associate with people and groups who value essentially the "reasonable breeze" mode that keeps life flowing through extant systems. "Natural disasters" may sometimes be justified to help clear out the way-too-old (e.g. systemd or SMF), but they should be rare; systems can only tolerate major disruptions like that once or twice a decade.
Linux has an "anything goes" approach, which is usually more symptomatic of the age/maturity of the crowd it draws in than a reasoned decision about where to fall on this balance. That's not necessarily bad, but it makes more of an experimental atmosphere than something reliable, trusted, and stable.
EDIT: I guess I have to clarify this statement a little; In Windows the concept of "logging" is up to the event manager, this mirrors journalctl. To be more precise they seem to focus on desktop operating systems with an example being the unit file itself: "The syntax is inspired by XDG Desktop Entry Specification .desktop files, which are in turn inspired by Microsoft Windows .ini files.", maybe you prefer talking about firewalld and it's "Zones" which are clearly inspired by desktop use. (Laptops more specifically).
There was something that I'm forgetting though, a terminology that was only used by microsoft to describe something and systemd used exactly the same terminology. It was very esoteric terminology though, I'm trying to find a reference.
