As a kinda strange reason, I like them in contrib because
they demonstrate a nice simple example of how one can write a
contrib extension.

This module has simple functions that take a string or
two and return a string or number. Most of the other
contrib modules do tricky stuff with weird types or
indexes that make them rather complex to use as
a starting point.

If they were to be moved out of contrib, I think it'd be
really nice if someone add a "hello_world" contrib that
demonstrates a bunch of simple operations in C to be used
as such a model.
