Back in March I investigated traffic to & usage of search.wikimedia.org bridge, and found that old Apple Dictionary versions out there (like, more than a decade old used by ~330 IP addresses/day) were broken because they're hitting a non-secure URI and weren't coded to deal with the 301 response. At some point Apple switched to using MW search API directly in the Dictionary app.
We were maintaining this tech debt as of 2021 (T289224) but we can just shut it down and archive the codebase. Anyone using the legacy, broken Dictionary app isn't getting any results anyway and we can't disable HTTPS just for that domain.

- T289518: Code Stewardship Review for search.wikimedia.org can be resolved since the code can be archived and the service shut down
- T195436: Make a search portal at search.wikimedia.org can be worked on since that domain would be freed up
