For them they know enough to run the compiler.  They can simply click “Build” in an IDE.  Sure they need to understand the compilation model, as implied by the programming language, but they don’t need to memorize all the list of flags, etc., that are needed to run the compiler from the command line.  I’m not saying that everyone doesn’t know how to use the compiler directly from the command line, but I’d argue that a very large constituency of developers (who clearly have demonstrated that they can write software) don’t have this knowledge, nor do they need it.
