A better analogy would be a modern day SSB [0] proposing a constitutional amendment to officially rename federal offices by their standardized acronyms, e.g. "President of the United States" to "POTUS", "Supreme Court of the United States" to "SCOTUS", etc., especially as this would be an equally superficial distraction from this hypothetical neo-SSB's real goal of replacing all Congressmen with AIs and relocating the capitol to Kansas City.
As it happens, "green" exists linguistically, so one is not compelled to wax artfully about the "yellow-blue blades [of grass] laced in dew". However, it used to be that the only way to talk of "orange" was as "yellow-red" or similar, until the simplifying convention of a new word for a distinct entity took hold.
Edit: Further, Urbit's equivalent of the Sunflower State Congress plan gloms enough together that an atomistically novel domain specific vocabulary is at least as useful.
Edit: As one effectively lay to the many disciplines of the professional field of computation, I use this forum to advertise my continued interest in a critical audit of Urbit. If Keean Schupke and Thomas Lord can probe the depths of Carl Hewitt's ActorScript [1] (the true standard for any so accused "obscurantist" software), then a fortiori Urbit's Anathem barrier [2] can be only semi-impermeable.
