Revision 4f06a45252465792447f80b6559b17c4c4e9712c authored by Daniel Vogelheim on 10 April 2018, 13:07:39 UTC, committed by Chromium WPT Sync on 10 April 2018, 13:07:39 UTC 
Implement deprecation of content type sniffing for workers.
 
Allow control of the deprecation via runtime enabled features, with a first
step for logging a warning to the console, and the second step to block it
outright.
