Making it optional makes it useless. Name the programming 
languages that implement named parameters this way, and I'll give 
a giant list of ones that don't. You can make this exact argument 
for basically structs and everything else. When you use a library 
you are at the mercy of it's owner. I've seen some people 
maintain an API that just literally changed the style so 
basically every single line that used that API now had to be 
updated. It was a minor version too 3.0 -> 3.1. Let the user 
decide when those cases are for themselves, and they do so 
knowing the risk, like with everything else they may have to 
update their code to match.

There's already enough attributes, we shouldn't be adding more 
needlessly. I don't think this is a good enough reason to.
