Hi,
I believe one can (and possibly should) use these "page redirect titles" as
an additional (but low ranked) source for our growing search algorithm.
Think of a user typing a page title that exists as a redirect on the
English Wikipedia. It would be pretty cool if the related Wikidata item can
be found when using the same search term on Wikidata.
But as Lydia already explained: The semantic relationship is weak.
Especially on the English Wikipedia that usually does not delete redirects,
no matter how "wrong" they are. This is different in other wikis. The
German Wikipedia for example usually deletes redirects that do not have a
strong semantic relationship to the target article. The probability that
these German redirects can become aliases on Wikidata is much higher, but
still not high enough for a bot import.
Best
Thiemo
