One line initialization of multiple variables

Is there any reason why MS did allow for a one liner to initialize multiple variables. Take this for example:
This is great if I want all the integers to be 0, but if I want them to be a different value then I'm forced to set those variables individually. Grant it, I'm able to use the : character to set all those variables on 1 line, but I'm still forced to individually set those variables. What I'm wondering is why they don't allow for something like this:
This is more of a discussion rather than a question, to see if maybe y'all have some opinions on why they didn't allow for that.
