There’s something to be said about publishing blog posts as Jupyter notebooks straight to your GitHub. A strong argument won’t need decoration.
Typography, layout, and presentation counts for more than coders such as myself will ever admit publicly :)
This has nothing to do with the parent comment's topic, which was about using computational notebooks as blog posts, and is in effect "complaining about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage" - which the guidelines explicitly forbid.
