Everyone jumped on the only-use-rem train when mobile started dominating because it provides relative units that scale better rather than absolute pixels. In practice it doesn't really mean much outside of blog-like text so when doing layouts it's more of just a standard everyone agrees on using everywhere because it's easier to stick to one for consistencies sake and it does the job. I don't think many frontend devs ever test zooming text using a browser anyway, their main concern is variations in screen sizes, basically device variation not manually zooming text. But I get the arguments to limit it to text.
