I think you need to sit this one out. This sort of vacuous pedantry does no one any good, and ignores that it's perfectly fine to model and treat some calls are synchronous, including plain old HTTP ones. Just because everything is a state machine this does not mean you buy yourself anything of value by modeling everything as a state machine.

I think you should have sat it out actually. The “vacuous pedantry” is responsible for a huge class of bugs in computing. It’s juniors misunderstanding how these processes work or in any case developers not understanding where the wait is that cause all kinds of race conditions. So yes you absolutely buy yourself something by understanding and accounting for how the processes you’re wielding actually work.
