For many programming languages the line count of "hello, world!" program is exactly one.

So you can deduce something just from a line count of simple program alone - for one such deduction is an answer to a question "are there at least some attempts to provide useful defaults?"

I agree that a Hello World is fairly useless example for anyone already familiar with programming languages. Perhaps something like a Fibonacci function should be the de facto short syntax example, as is common in functional languages. More useful though would be to have an example of how composition data structures work in the language - standard example could be a binary tree.
