Miriam Webster lists "statuses" as the plural form.
You apparently do not know how lexicographers (the professionals who compile dictionaries) work. They don't invent language, words, or word forms, but document how people use words in actual practice. This has been their modus operandi since Samuel Johnson's first English dictionary.
That's why radius has its 1st plural as radii, and a 2nd plural as radiuses, but for alumnus, the only plural is alumni. The dictionary documents how our dynamic language changes.
People determine the growth and changes in our language. Latin is, for all but very specialized purposes, dead
