Why?
D inherited a silly rule from C where any arithmetic is promoted to int first.
The big difference is D doesn't do implicit narrowing conversion... so x + 1 becomes int, but then int to byte requires an explicit cast (unless the compiler can prove the range in that particular expression - this is called "value range propagation").
I think it has proved to be a bit of a mistake :(
