For me main benefits are

Wikidata editors decided to rename article (moves related to dashes, emdashes, brackets and similar are really liked by some)
See https://matkoniecz.github.io/OSM-wikipedia-tag-validator-reports/Schweiz%20-... that could be fixed with automatic edit rather with manual one thanks to presence of wikidata confirming the target of redirect.
Not all redirects are bad and should be automatically replaced. Sometimes they are there for a reason.
Example: the hamlet of Hurnen In OSM: https://www.openstreetmap.org/node/3099480616
It has a wikipedia tag of de:Hurnen, which is fine. It can be considered a placeholder for its own page which at the moment still redirects to the page of Eschlikon, which it is part from.
The wikidata tag was derived automatically from the wikipedia tag not taking this situation into account. So it's not a reliable source.
The correct handling here would be to delete the wikidata tag.
NB: the fact that the wikidata page has Hurnen and Wallenwil as alternative names of Eschlikon makes me seriously question the usefuleness of wikidata.
