You can think what you wish, but the latest Acura update, solved the vast majority of the issues ... not related to the iPhone itself.
I agree it should work with an iPhone X, the same as it works with an iPhone 8, but I can't speak to the X, as I don't like it and don't use it.
I can tell you, if you use an iPhone 8 and clear everything out of the system, the infotainment system will work reasonably well, with few, if any, interruptions.
As I've said numerous times in this thread, there are lot of "user error issues", to go along with everything else. I'm not going out of my way to back Acura on this, I'm part of the Class Action Suit ... but this latest update, is a major improvement and makes the system usable, far in excess of what was even possible, prior to Beta 13 and Apple's upgraded CarPlay.
