Maximum size (in bytes) of the com.google.rpc.Status proto that a self-service error code can be serialized into.

We choose this value with the following considerations:

• The serialized error Status proto is packed into a io.grpc.Metadata together with the error description, which is then enriched with additional gRPC-internal entries and converted into HTTP2 headers for transmission.
• The default maximum gRPC metadata size is 8KB (for both clients and servers). We MUST ensure that we don't exceed this value for error-returning gRPC metadata, otherwise INTERNAL errors may be reported on both the client and server.
• The error description is packed twice in the serialized metadata (see ErrorCode.asGrpcError and how it creates a io.grpc.StatusRuntimeException).

Conservatively we allow a buffer of > 3KB for gRPC and gRPC->HTTP2 internals overhead. (considering a MaxErrorContentBytes maximum Status proto size and limit the cause description size).

Note: instead of increasing this value, consider limiting better the error contents.
