I think this is a pretty dangerous attitude, and it is really the only thing wrong with Linux, and probably leads to replacement of simple structure and functionality with a complex software suite that is merely more convenient, like systemd. "Let's change this thing because we want to, because it will improve performance 0.0024%"
Feature creep is what happens when restraint was not exercised.
IMO, since it really doesn't matter what the filesystem looks like, leave it be for standards and compatibility. Seriously, it takes, idk, maybe, a lack of humility to want to change fundamental characteristics of UNIX when the reasons for doing so are a little capricious.
I'm not really talking about the parent, fwiw. I'm talking about the crowd and ochlocracy.
There's plenty greybeards that for them "Linux" is a full screen terminal running emacs on decade-old hardware. "I don't use antialiased fonts, why the hell should I care about decent HiDPI support?" And then protest every time some working group tries to modernise and improve the Linux desktop. You see them every time on this forum.
I'm a greybeard, I've used Linux full time on the desktop for 20 years. I don't get this conservative, "we don't need it" attitude.
For those of us who ran small-disk NFS workstations back in the day having the split and a common /usr was no quirk and very useful. (There were also diskless (Sun, OpenFirmware netbooting) workstations: common /bin, /usr, but per-machine /var on the NFS server.)
The article states:

Yeah, except if you have a fleet of several hundred or thousand workstations to provision. "Cheap" is relative, especially if you're an academic institution.
