__declspec(empty_bases)can only be applied to classes that you control. It cannot be applied to classes in the STL nor those that are included in libraries that are not also re-compiled with the EBCO layout.
Correct: an empty_view is not not empty size Get the number of elements in the view, which will always be 0. C++ staticconstexprsize_tsize() Parameters None. Return value 0. See also <ranges> emptyrange adaptor single_view view classes...

points to its initial member, which is why the requirements for a standard layout type include "has all non-static data members declared in the same class (either all in the derived or all in some base)" and "has no base classes of the same type as the first non-static data member"...
A class with a single non-static data member of typecharis also 1 byte in size: C++ structStruct1{charc; };static_assert(sizeof(Struct1) ==1,"Struct1 should be 1 byte"); Combining these classes in a class hierarchy also results in a class that's 1 byte in size: ...
