The idea is to keep the current ORES extension active on MediaWiki deployments, migrating its backend calls from ORES to Lift Wing.
Some notes:
- As described in T312518#8108190, the PHP code change shouldn't be too hard. The extra difficult point is that we'll need to add meaningful HTTP Host headers to the extentions' HTTP calls.
- To ease the transition and the code change, we should make the revscoring-models' output equal to the ORES one. See T318932.
The goal of the task is to update the ORES extension code to support Lift Wing, and then configure it via MediaWiki deployments.
