A maximum line length of 80 characters is RECOMMENDED.
This is a terrible recommendation. It defeats the purpose of semantic line breaks if you insert them for non-semantic reasons as well. It also makes editing much more difficult. Let client software handle soft line wrapping, so the user can customize it as it makes sense for them. If your client software doesn’t handle soft line wrapping in a sensible way, find better software.

The idea is to keep significant bits of thought under 80 characters.
That should be out of scope for a spec which “MUST NOT alter the final rendered output of the document.”
It’s not the place of a markup language/spec to influence writing style.
