I would argue that effectively using tools you don't fully understand is one of the primary skills of software development. If that were not the case, we would spend about 95% of our time taking online courses and following tutorials and 5% of our time getting work done. Instead, it's the reverse. But that does not negate the value of deep expertise in one or several chosen sub-disciplines. Being "T-shaped" is a thing.
