I explicitly said firefox is not like this (and browsers are bad) and I don't really see your point with blender (though don't use the program so I can defer to you knowledge), I even said I am a heavy emacs user and so don't believe in dogmatically following 'do only one thing well' principle.
All you have to demonstrate is what is the value.
> But the unix philosophy thing came not from a time of blender, firefox and systemd but a time of ls, cat, grep, xargs and co
are you trying to say ls, cat and grep have been superseded? this is absurd these tools are still useful and not replaced what is your point here what are you trying to establish?
My question would be where is systemd a better experience or easy to work with then openrc, have you ever had to disable any of the systemd defaults services such as resolving or networking and had issues with the way a distro set things up. I don't know how you can claim you have never an into an issue with it given that any piece of software you will run into issues with.
I am also arguing more for openrc which is a newer project that has notions of dependence's and such.
If I may show where I think 'do only one thing well' is violated and correctly so is emacs (at least in part), for by having emacs as what boils down to a constant text interface I can use generalized text editing, searching and deriving buffers all in one program not having to configure anything else, my editor is my console and I can use my editor tools in my console even the ones I make.
So where is it demonstrated that the coupling is a boon that out weights the cost.
