I don't see the "evented runtime vs. evented API" issue as boring. This kind of thing is the core of any application you are going to build; it's hardly a minor or nitpicky issue.

Using non-blocking APIs requires you to turn your application "inside out", putting state that would normally have been on the stack into a state machine. You wind up in a maze of callbacks and low-level details.

This kind of thing might be appropriate for writing high performance code in C, but it's a mystery to me why anyone would want to do it in a higher-level language.

It forces you to keep your methods short with reasonably appropriate boundaries between them. Good programmers should be doing this anyway, but an event/callback API at least prevents you from writing a 300-line "do everything" method.
