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.
It doesn’t need to be good to replace jobs, as long as there are no consequences for the people making those decisions.
I’ve lost count of how many “oops, it was AI’s fault, not my fault!” stories I’ve heard, even within highly regulated fields. Like, lawyers submitting documents with completely fake citations, and then…no real consequences. Seems to me like that should be cause for immediate disbarment, but no, apparently not.
