You can render frames directly to a video file (ffmpeg option), which I suspect a lot of beginners or casual users do. You can also use the compositor to turn a prerendered frame sequence into a video file. Lastly I suspect most users prefer video editing in another program such as Resolve. I get the inpression the VSE is nit used much because it occupies a narrow space of “need some basic cutting abilities but no transforms, titles, or effects”. Hopefully someone will continue the work of improving transforms and effects and even add 3 point editing someday
