Prior to deploying language variants support for the summary endpoint, here's the checklist of dependencies:
- Verify page previews set Accept-Language T185139
- Verify VE sets Accept-Language T198186
- Verify apps set Accept-Language (verified on the sync up meeting)
- Verify feeds and reading lists DO NOT forward Accept-Language to summary during hydration. We do not store the summaries and generating them on-the-fly for hydration of the feeds would be prohibitively expencive.
