In connection with this question which is now "on hold", there is the message "If this question can be reworded to fit the rules in the help center, please edit the question or leave a comment." Although I think the question has already been adequately edited to get it re-opened, I seem to be the only one voting for that. Is it appropriate for anyone other than the author to edit the question even more? (It risks mis-stating the author's intentions.) I happen to think it's actually a nice code-challenge problem, and would like to see what other solutions people might have.
This whole post is just my opinion as a Stack Exchange user, and I am not speaking as a moderator here, and definitely not "the moderator who closed the linked question at the request of another user".
I believe that posts are okay to be edited by anyone, especially if (on this site) it makes it a more suitable or fair or accessible golfing/coding challenge. Of course, for substantial edits, it's more polite to propose edits as a comment first, and gather community consensus, but once such consensus is reached, I believe it's okay to edit the post directly.
If the author of a question feels like an edit misrepresented their ideas or positions, they are free to make further edits. So don't worry about that.
