I'd like some wider opinions, particularly from UX designers, on the following issue: in MediaWiki's login form on desktop, there is a link to a login help page. By default it links to "Help:Logging in", which exists on most Wikimedia wikis but which is likely not existing in a brand new MediaWiki installation. 

I was comfortable including this link by default because I think it's reasonable to ask wiki administrators to either create a login help page or link to one they like. However, some people find this unacceptable, and would prefer to link by default to the help page on MediaWiki.org.

I think this is not so bad, and there are drawbacks to both. However, I think it's better to not link to a help page on a completely different site. Users, especially casual non-technical users, won't understand what "MediaWiki" is or why they were sent there instead of to a help page on their wiki. This seems likely to confuse, and we should put more of the burden on site admins to deal with the link as they see fit. 

The relevant patch is https://gerrit.wikimedia.org/r/#/c/83220/ and the bug to comment on is https://bugzilla.wikimedia.org/show_bug.cgi?id=53888 if anyone can chime in.
