+
+Note that this is the only place in src/core where we allow
+use of the C++ standard library (i.e., anything in the `std::`
+namespace). And for now, we require that any use of the
+standard library is build-time-only -- i.e., we do not allow
+run-time dependencies on libstdc++. For more details, see
+[gRFC L6](/grpc/proposal/blob/master/L6-allow-c%2B%2B-in-grpc-core.md) and
+[Moving gRPC core to C++](/grpc/grpc/blob/master/doc/core/moving-to-c%2B%2B.md).
