Should double negative in English become recognized formally?

I’ll try to explain through examples. Usually when you tell someone you don’t want tomato you’ll say:
“I don’t want any tomato” or “I want no tomato”

But

If double negative is recognized officially as an addition to our English repertoire we can also say:
“I don’t want no tomato”

Why won’t the government just accept double negative as an addition to English grammar? It’s already well-accepted by many people (bar some grammar Nazis), and since language keeps on evolving there’s no reason to deny this.

Additionally, I think the word “ain’t” is also pretty versatile and should also be recognized officially. For example, you can use cool language usage like “I ain’t got no problem with you”. Should it also be recognized officially?

This type of English language usage has been existing for a long time, popularized by the media, and many people themselves have used it so there no use to deny this addition.
