Note also that the guidelines are in the wiki for convenience, but
there have been at least two efforts to move them to a "better" format.
And I would truly love to have a companion set of documents which aren't
guidelines but which expand on them and document things like this.
Whether that ends up being maintained as part of the guidelines or
separately hasn't even been discussed yet, but at least you'll be able
to send a PR in pagure to get something updated.
