I'm curious if that's mainly specific to English. As an Arabic speaker, tremendous care and effort has been taken to preserve Fuṣḥā (formal/High) Arabic throughout the centuries. Language and conjugation that sounds wrong is often shunned or mocked, even though it may partially be spoken in day to day speech in certain contexts. However, the distinction is always there, and such language will not be accepted in official discourse, let alone avenues like poetry and literature.
