Officially, yes, but in practice, no. I'm not guessing here, I'm speaking from experience. Hill has also obviously figured all this out before beginning this project, and he explicitly talked about this in one of his videos.
I do agree the HC50 is a very long way off. Since they're trying to be almost completely vertically integrated, that's a massive certification issue that will take many years and tons of money. And the early HX50s may be dangerous due to limited testing, but we'll see.
