A key difference is that it sounds like you need to create and otherwise interact with that sort of code on a regular basis.

Most devs spend most of their time, all of it even, on tasks that are either naturally sequential or don't benefit from threading enough over the safer option of multiple independent processes, so when they do come across a problem that is inherently parallelizable and needs the highest performance it is not a familiar situation for them. Familiarity can make some rather complex processes feel simple.

The same can be said for event loop driven concurrency, for those who don't work that way often the collection of potential race conditions there can feel daunting so they appreciate their chosen platform holding their hand a bit.

Holding hand is useful until it is not. It often has big trade offs.
