Yes.

I strongly disagree with this. If the binaries are missing, then the
setup done using systemd tools in rpm scriptlets would not happen. So
e.g. if depending on the order of installation, systemd was installed
first, systemctl preset would work, but if systemd was installed
later, systemctl preset would turn into a nop. I really don't see the
point of having systemd-filesystem, when almost everythin which could
depend on this package, would also have to depend on systemd for the
tools.

Yeah, I see that.
