Is this done by the kernel? Means, does systemd use this kernel
feature? Arch's and Gentoo's sysv init don't do it. In my experience -
I have tested this on Gentoo and on Arch  - these parallelizations make
booting a lot slower particularly on older and slower systems.

Is this really an issue? I mean, Gentoo's init system is aware of
dependencies. But I really haven't missed this on Arch. I usually know
by myself, that apache first needs a network being set up. And I have
the impression that this makes Arch's init system slightly faster and
more KISS like.

This would make it even worse, if apache needs to be patched. And if
apache is patched can this behaviour of systemd be turned off?
