chromium-wpt-export-bot · arichiv · web-flow · commit 1691e2c6a184 · 2021-09-16T09:19:03.000-07:00
Now that we've cleaned up the array indexing that was blocking this, let's move forward with removing this unused client hint. This is a part of a series of CLs to re-factor the client hints code: (1) Label hints with legacy names (2) Fix the naming of (unlaunched) `lang` client hint (3) Consolidate client hint name lists (4) Migrate from array to map indexing for client hint names (5) Remove (unlaunched) `lang` client hint Bug: 1227043 Change-Id: I57404516cd1f39f738f0fbd7c202de7adf063d98 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3160286 Auto-Submit: Ari Chivukula <arichiv@chromium.org> Commit-Queue: Matt Falkenhagen <falken@chromium.org> Reviewed-by: Matt Falkenhagen <falken@chromium.org> Reviewed-by: David Dorwin <ddorwin@chromium.org> Reviewed-by: Yoav Weiss <yoavweiss@chromium.org> Reviewed-by: Dominick Ng <dominickn@chromium.org> Cr-Commit-Position: refs/heads/main@{#921893} Co-authored-by: Ari Chivukula <arichiv@chromium.org>
