         Right now, we set these to lint warnings so:

         DO NOT ADD TO THIS LIST.

         We did this so we can land lint in automation
         and not fail everything. -->

         We want all lint warnings to be fatal errors.
         This is the list of checks that we've explicitly
         set as errors. Ideally, once we have no more warnings,
         we switch to the `warningsAsErrors` lint option
         (bug 1253737) rather than listing everything explicitly. -->
