Please let me disagree here.

Exceptions + RAII are super useful for reliable software, as 
shown in C++.

Subtype polymorphism is basically required for any type of UI.

Unrestricted CTFE? On the page it reads:

That's 3 more attack vectors etc.

The list goes on and on, I think it has variable-sized integers
