That does seem rational, because the compiler can't know if new[]/delete[] will
be used outside of the DLL. And it seems adding dllexport does trigger MSVC to
generate vector destructors. The comments to
https://developercommunity.visualstudio.com/t/delete-calls-scalar-deleting-destructor-instead-of/346875
also suggest so.
I'm not yet familiar with "local vftable constructor closues" though...
