snow I think you need the config change from #1750

I think it also need a bazel build fix. Let's merge yours first and I'l deal with the incremental envoy upgrade here

Mysterious iOS failure - @keith any idea what might be happening here? https://github.com/envoyproxy/envoy-mobile/pull/1754/checks?check_run_id=3435665501

ughh. I guess my testing wasn't enough, we can do envoyproxy/envoy#17875 again for now

closing in favor of #1760
