Apparently there's an issue where compiling grpc with -std=c++17 fails unless the clang version is at least 11. Hopefully our default clang version will be increased to that soon, but until then we need to work around this problem by setting an older C++ standard. It's unclear if using C++11 causes further issues, but compiling is better than not compiling, I suppose. Contrary to the linked bug report, the darwin stdenv doesn't exhibit this problem for some reason.
