Do we really need this to be cherrypicked? Is anyone wanting this feature in the upcoming release? Thanks. |

This change allows Istio users to depend on a tagged gRPC release (instead of a commit hash) for resolving issue istio/istio#53532. We will get a week of internal testing to catch regressions before the 1.77 release, and I don't see any significant harm in including it. |
