I agree, this is the whole point of "Hello world", which is to show the boilerplate required to start a program capable of outputting text, as well as the actual code that outputs that text. It's also the chance to get the build tools setup, people forget that some of the 'boilerplate' is the actions required to build, which often are much more involved for newer tools and frameworks.

You can just say initially e.g. when I learned C++ that "#include <iostream>" can be "mostly ignored for now, but just know iostream stands for Input / Output stream, and this line is necessary to e.g. output with std::cout"; and there are no scars left from this.

Some scars... as cout << was always a bad idea, and taught people early on in their C++ development that being overly clever with operator overloading was expected
