You do realize that this is kinda bad, right? No english spelling reform ever took hold because of the vast difference in english pronounciation. your "nite" might completely differ from the aussie version of "night". so you'd have to declare one dialect to be the supreme one. That'll be fun :)

Secondly: Gender and gendered terms are sociallinguistic conventions. And they do not follow stereotypical gender norms. Often they radiate outwards from gendered terms for humans and then encompass things that follow similar sound structures. sometimes gender is historically motivated: Spanish generally divides things along the lines of "does it end with an -a or -o" and then assigns gender. But terms like "diversidad" stem from female latin words and retain their gender. "problema" seems feminine, but stems from a male greek word and is therefore male. Not because "tHe MaLeS aRe ThE PrrObLeM", but because ancient greek sound structures classified this as "male-sounding" and Spanish ran with it.

In German, "das Mädchen" (the girl) is neutral. Not bevause all girl are secretly enbies or equivalent to possesions, but the diminuitive "-chen" turns things neutral.

all that to say: "Why dont they do that" can always answered with a resounding "Why dont you have feature x?". Why doesnt English use eventiality or cases or dual and trial numeri or tones or different conjugations depending on registers? Because the language didnt develope that way.

I pronounce epitome as epi-tome and refuse to change it no matter how many times I'm "corrected"
