You may be right. I think it was a mistake to insist on public domain Help pages, and that we are reaping the harmful consequences of that decision. But to fix it would require acknowledging that a mistake was made, and sometimes people are resistant to that.
I disagree - PD help pages are a very good idea. However, it is a mistake to think they will be of any real use until we provide a workable method of distibuting them. I think it is a fairly safe assumption that if there was an easy way to import the default help pages into your local wiki, in the appropriate language(s), then that would be sufficient encouragement for the current pages to be tidied up (if, indeed, that is necessary - I haven't looked at them for a while) and, more importantly, widely translated.
I don't think think the solution here is to import existing non-English help content from elsewhere, or to try and encourage a translation drive for the help content, without having an export process in place.
Seems we can all agree on this, so we're left with #1 and #2 for now.
So... no interest/ideas/suggestions on those two points (priority pages and manual pages)?
I'm afraid translation isn't my area of expertise. It's been noted that "English is the working language of the Internet", though, and my attitude toward those who seek to administer websites tends to be, learn English or GTFO. But you seem to be on the right track as far as prioritization is concerned; focus on the most-viewed pages first.
