I'm one of these codey designers. The madness that exists in modern design teams (I used to manage a team of 50!) is insane. There's a lot of time spent on "design systems" in Figma. Very generally Figma is not the website, and the effeciency additions of building tools there is a lost cause.
Modern CSS and your JS frontend of choice is a lot quicker and more powerful for component building and general design work. There's way too much to do with media break points and tokenization there. There's a misguided group of designers that are learning a lot of esoteric Figma features that don't translate into something users will ever touch.
10 and 15 years ago designers needed to learn the code part too. Somewhere along the way we put them in a corner and made learn these prototype tools.
