Completely, utterly and factually wrong. Steven Spielberg, a director you may have heard of, very specifically shoots many of his films with above average grain. In fact he refuses to shoot any films using digital cameras, he wants film grain *that* much. I'd say that's "intentional".
Michael Mann shoots digitally and sometimes cranks the gain up on his cameras to introduce additional "grain" into the image. This is a practice that videographers generally strive to avoid under all circumstances and he does it on purpose. That's certainly not Mann suffering from "technology limitation".
And there's of course 300, which was shot basically grain free and had masses of grain applied digitally. That's "intentional" use of "technology" to deliver grain.
Even George Lucas had ILM add some grain to EP:III because the Sony 1080P cameras were too sharp for his liking.
Generally speaking, on any recent, current or future films if there is grain it is not due to any limitations. If a director wishes to shoot a film with little, or even no grain, that's completely doable.
