Sure. My point is that 'pretending that the distinction doesn't exist' (aka 'abstracting away from it', in less loaded language) does in fact work. Go's concurrency model is perfectly usable and successfully reaps many of the advantages of M:N scheduling.

Let's look at a less loaded example:

"Trying to remove the distinction between stack and heap allocation will not work, and you'll only be pretending that it doesn't exist."

It's true that on some level there's going to be a distinction between stack and heap allocation. But it totally does work to abstract away from this distinction ('pretend that it doesn't exist'). Go, for example, will usually allocate non-escaping values on the stack, but unless you are tweaking your code for performance, you'll never have to worry about this.
