Since clang is able to compile this struct and do everything

I checked, and the reason is that D and C++ use a different ABI
wrt. by-value passing of non-POD arguments. C++ indeed passes a
reference to a caller-allocated rvalue, not just on Win64; that
makes it trivial, as there are no moves across call boundaries.
But your proposal may imply changing the D ABI accordingly.
