Excellent questions&mdash;and thanks the specific examples!

The concerns around redirect and disambiguation pages are more for communities that have created a redirect page for all possible misspellings or have more disambiguation pages than articles. Search engines consider the ratio of bad/thin pages to good/interesting/relevant pages in their algorithms and can devalue the entire subdomain when the bad outweighs the good.

Neither the first nor the second use case should cause an issue as implemented on Acepedia. The F-14 disambiguation page does not have a ton of content but is explains page relationships and links to internal search. I would not expect pages like this to rank in organic search but there is still real value to human users.

On the last point: there is a ticket in our backlog to tackle that. MediaWiki is not the best at handling canonical tags or redirect chains, so lots to clean up behind the scenes before we could build a solution. But it is on our radar! :)
