None of the changes here directly affect any unions, only structs, so 
maybe the assignment operator could have been kept? If a struct contains 
a union, then you can't use the compiler-generated assignment operator, 
but you can still define your own and use something other than = to copy 
the union variable from the other object to this.

However, maybe SANITIZE_OBJ needs to work across a range of types that 
includes unions, and so you need to add a method everywhere to allow 
uniform treatment. Even so, I didn't see any set methods being added to 
unions in this commit.

FYI, the naming convention adopted in the C++ standard library is 
"assign", eg in std::string, so it might be a good idea to follow that.
