The "help desk" (place where help panel posted questions to) used to be an integral part of the help panel experience. But the help panel has evolved -- it's now a conduit for showing guidance when editing, on some wikis it posts to your mentor and not the help desk, etc.
The code for the help panel contains a check to see if the configured help desk title exists, and if not, it won't display. This means for suggested edits, the user won't see guidance, as was the case on Korean wiki this month (T239695).
My proposal is to remove the check for help desk title existence. Instead, we can still show the help panel but we will just hide the section that allows asking questions (unless it's configured to post to a mentor page, that is)
