The question that led to this, https://unix.stackexchange.com/questions/480616/creating-a-new-composerized-latest-drupal-project-with-local-drush-and-all-desir, was moved to the Unix site. It has been answered, with a lot of information that is tangential to Drupal, and specific to general server administration.
On one of the answers, you yourself linked to a question on the Dev-ops Stack Exchange site, declaring it to be useful background information to understand the answer.
And that's exactly the point - a place for everything, and everything in its place. We don't need to answer the general Dev-Ops questions here, because there are existing websites, indeed within this very network, which cater perfectly to those.
So going off the only example given in the comments, and the discussion you and I have had about this over the last few days, I'm going to go out on a limb and say: no, we don't need to relax the rules about Dev-Ops questions here. We already accept Drupal-specific Dev-Ops questions that otherwise fit into the guidelines, so there's nothing really to change anyway.
If you have a question about some Drupal-specific configuration of one of these tools, by all means ask it here. But if you have a general question, like your previous one about setting up an entire *nix development environment in one go, please don't ask that here. For a start it's actually much too broad for our format, but the main point being that not all of it relates to Drupal, so it's simply not a good question for a Drupal-specific Q+A site.
