This misrepresents the systemd position. Not using a shell is faster,
but that's not the only reason to avoid shell. Avoid shell in cases

This doesn't seem to match the experience of other people.
You made similar questionable claims earlier (see my reply then at
). You imply systemd design decisions are based solely on boot speed, to
the detriment of other features. This claim is false. You may disagree
with those design decisions, but it's a fact that they were chosen
because they were (and are) considered good for goals like
maintainability rather than just boot speed. You make claims about
"hard-coding policy into C", but have given no examples of concrete
problems or limitations. What is actually hard-coded so hard that it
would cause problems?
