It depends on your end goals, if your target is to find a job, implement some feature without going into too details. Not every people like to deals with the implementation details. Being a generalist is the road.
For example, many people just know how use React components, Angular components. But that’s ok in many jobs become there is no strict UI requirement on many jobs.
However, If your endpoint is to write components with design system / customise / optimise the components a little bit, you really need to understand how CSS and JS works.
The biggest pitfall I think is career development, if you are too generalist and your knowledge just stays on the surface, you just can’t solve some problems with technical complexity. It is hard to know what you don’t know … and some problems need expertise.
