Setup for 2023-12-31~2024-04-16:
- proxy https://phabricator.wikimedia.org/robots.txt + custom text via Cloudflare Workers
Setup as of 2024-04-16: Load extension via rSANDBOX/PhabExt
Possible reinforcement:
- Pray to Upstream to implement proper robots.txt management
- Host robots.txt file elsewhere and proxy it via cloudflare worker
1 is probably the way to go but too lazy to file a task.
