You have a point concerning the text files. (Although I would be really interested to see an example where efficiency of text files is insufficient on modern hardware.)
However "multiple orthogonal multiple orthogonal executables" is just a strawman: their interfaces are unstable and non-straightforward, aand communicate over standardized IPC mechanismsnd one can't reliably replace one of them with an alternative. It's technically true but in practice not. This effectively makes it a huge, inflexible, not-easily-verifiable blob with wide permissions and, potentially, many bugs.

I've never seen that anyone could replace one systemd component with an alternative implementation. Did you?
