Our positions diverge because you take the extra-formal specification in mathematics as basis, and then say, "nah thats too formal", broadcasting is more natural. On the other hand I take elementary to undergrad mathematics as basis and say that rules about adding (using a standard '+' symbol) a scalar to a vector in numpy via broadcasting is confusing.
