That’s not quite how a natural language like English works. There’s a bunch of mess and idioms and “technically correct” is almost never how things start to get used in real life. Thus often it happens that whatever is the majority becomes the default, like for instance cisgender is a concept that almost never has to be used because 99% of people are cisgender. Not that it’s not a valid term, it’s just a term that’s almost universally redundant.
