> Are there a lot of people who learn only web frameworks?
Yes, because many people learn web development through bootcamps or other such courses (modern web dev is not usually taught in college, in my experience) which rush you to "job readiness" thus incentivizing using React over vanilla JS since most web dev jobs use React nowadays.
What would a college that aimed to teach Web Development as a specialty actually look like?
People look down on bootcampers, but it always feels to me that 99% of what is taught in university programs is similarly only useful in specialized situations. The actual good thing is having had to sit down and write a lot of code before anyone lets you touch anything.
