I did not run any big c/c++ projects but, I ran, big php/python web projects. Dependencies in these kinds of web projects are messier than desktop/system applications. And it is not unmaintable as you are implying. So reimplementing instead of depending on maintained projects with its own teams is getting that burden to yourself. Also you can put hard dependencies with version requirements. We may look into big c/c++ projects like Firefox, blender, chrome and many others and we can see that dependencies are really managable and maintable. But yet again you may argue that using reimplementation of a json parser in a code base is simpler. It's personal choice and I belive it is not a good engineering practice. Still there is no good case for imlementation of any subsytem of linux in systemd.

Also systemd is very dependent on many other libraries (optional or mandatory). Adding json as an internal implementation instead of using an outer dependency is not justifiable with "dependency control reasons". From the readme: glibc >= 2.14 libcap libmount >= 2.20 (from util-linux) libseccomp >= 1.0.0 (optional) libblkid >= 2.24 (from util-linux) (optional) libkmod >= 15 (optional) PAM >= 1.1.2 (optional) libcryptsetup (optional) libaudit (optional) libacl (optional) libselinux (optional) liblzma (optional) liblz4 >= 119 (optional) libgcrypt (optional) libqrencode (optional) libmicrohttpd (optional) libpython (optional) libidn (optional) gobject-introspection > 1.40.0 (optional) elfutils >= 158 (optional) make, gcc, and similar tools During runtime, you need the following additional dependencies: util-linux >= v2.25 required dbus >= 1.4.0 (strictly speaking optional, but recommended) dracut (optional) PolicyKit (optional) When building from git, you need the following additional dependencies: docbook-xsl xsltproc automake autoconf libtool intltool gperf gtkdocize (optional) python (optional) python-lxml (optional, but required to build the indices) sphinx (optional)
