I'd LOVE to know where you're seeing this word used at such a high rate. As the parent of a trans non-binary teen, I *wish* all intake forms & applications would ask this. When my older two were applying for jobs, and then college, I never once saw a box to tick for "cisgender." And this was as recently as 2019. In my experience, they never do ask. For my trans non-binary teen, I can only select "male" or "female." Which is kind of hard to do if you have an intersex child who's neither male nor female, or some combination of both, or is trans non-binary. Words like "transgender" are necessary - necessary to distinguish from "cisgender" - because that's the only way trans people can get the medical care (and health insurance coverage) that's necessary for their mental health and physical bodies. It may seem excessive to you, but honestly, it's merely an inconvenience or aggravation for you. Something you're likely to get over. For trans people, it's literally a life saving thing.
