Only for some languages, and that cost should be far far less than running a separate process, shipping json over pipes, and parsing the json

I think that many modern programmers find this more ergonomic than a C ABI is part of what he is complaining about. Let's get comfortable with what is good, rather than make what we are comfortable with?

I agree in the abstract! I just emphatically disagree with characterizing a C ABI as "what is good."
