I read the slides, and I found it refreshing that you said at the end: don't create per-language bindings for the libraries shipped with systemd, but simply use a JSON parser for your language. That underlined that you've specified a simple protocol.

Also, there have clearly also been several attempts over the years to make a faster D-Bus implementation (kdbus, BUS1), which were never accepted into the kernel. It makes a lot of sense to instead design a simpler protocol.

There is clearly also a cautionary take about how microbenchmarks (here, for serialisation) can mask systemic flaws (lots of context switches with D-Bus, especially once polkit had to be involved).
