If I read that paper correctly, that's only valid if the object can be constructed without code being run - i.e. a trivially constructible type.

Since there is no limitation on the no_destroy type, you can create any type with it, including those which have a non-trivial constructor. Of course, you could use a concept to restrain it to only trivially constructible types, or you could omit the launder in an if constexpr branch and still be compliant.
