It works in other namespaces [[d:Special:AbuseLog/428942]] and also in all namespaces but only if you examine old revisions[1] [1] https://www.wikidata.org/w/index.php?title=Special:AbuseFilter/examine/157156654&testfilter=%22%23REDIRECT%22+in+new_wikitext+%26+%21%28%22%23REDIRECT%22+in+old_wikitext%29
Isn't this rather a bug with the AbuseFilter extension than with the WikidataRepo?
When you test the filter with "Examine past edits", it will match as expected. As Lymantria guessed [1], this might be due to the approach of using API for creating item redirects on Wikidata.
