Hi @MBaesken 
well, the mentioning of the flag in the man pages should not be removed, as the situation is unchanged. I do not backport the removal of the flag.   Fixing of at least a  row of the places your query shows was in the original change.
In head though, I think any remains should be removed if possible.
Thanks for the review!
