All code and examples are helpful, even if they don't directly make it into the official mainline. As @geekyi said, and also because people can learn from them and build things they need which may not match what Red makes standard. e.g., @Oldes' code may be extremely useful to some people, and even end up as an extension, for some circumstances.
They can also save Team Red research time. As long as Team Red knows they exist, they can leverage them as well.

Hi, I am still having problems understanding why a: "" or a: [] does not reset the content of A
From you comments at the end of april I have realized the "code is data" concept.
In this example:
red>> do code
== func [input /local s][s: "hello world" append s input]
red>> test "x"
== "hello worldx"
red>> body-of :test
== [s: "hello worldx" append s input]
I have realized that you are directly modifing the data/code structure.
But why a: "" or a: [] lead to nothing ? Aren't we linking a: to an empty block or are "" and [] "non existant", so it is like doing nothing ?

@GiuseppeChillemi for "how" - use
copy or copy/deep, for "why" - series! values are passed as pointers to some memory location, then you say something like word: [], it means "allocate some space for series, initiate it with some content (no content in this case) and make word point to that storage space" . So, in fact,word from that moment is always bound to static memory address, while content of that address could be changed and extended freely.
try print-it many times
>> foo: func [x][s: [no spoon] probe append s x poke body-of :foo 2 [no spoon]]
== func [x][s: [no spoon] probe append s x poke body-of :foo 2 [no spoon]]
>> foo 'whatsoever
[no spoon whatsoever]
== [no spoon]
>> body-of :foo
== [s: [no spoon] probe append s x poke body-of :foo 2 [no spoon]]
