English lexicographers have always been far too loosey-goosey -- even Oxford -- when it comes to immortalising uneducated or inept English.
The strength that comes from the language's adaptability would be fully preserved by admitting useful neologisms, but suppressing the crap instead of following any fad, no matter how ill-conceived, no matter what vandalism it does to words and constructions that are already useful, fully-formed, and precise in their meaning.
Unfortunately we've seen the results of trying to control language by authority. It fails, and to the extent it succeeds it stifles the language's vitality. The French are universally regarded as being so up their own asses about their language that they have to take a laxative to talk to themselves. And if they don't get OUT of their own asses their language will die, and "French" will be the name of a language spoken in Africa and Quebec, where authoritarian control has never been implemented (of the language, I mean).
