Well no its not. Science is not anyting that involves consensus, that is just democracy. They are defining a word here, and not based off any discovery or anything we learned experimentally.
We redefined the word because we liked the new definition better, because it felt more "useful" to us. That isnt science, nothing about that has much to do with science really, its just linguistics.
What is unique here is they decided to appropriate an existing word, and redefine it to mean something similar but new. Usually when we need new vocabulary words in science for convenience we dont redefine words already in common usage (particularly among non-scientists). We create new ones.
But yea, in the end, this wasnt really a scientific process in any meaningful way.
