Re: Roman numerals @Sequin
Roman numerals are like caps lock for numbers; they're a meta channel for conveying contextual information and a variation that adds to the rich texture of English.
after all we could do away with capital letters and punctuation because you dont use them in speech although perhaps theres a need to indicate a pause or the rising intonation of a question but why not go for the minimum and while were at it switch to phonetic spelling and get rid of any words whose meaning is so similar as to be all but identical to another
