Linker doesn't strip resource names when using -Qstrip_reflect

[EricLasotaRSE]

Description The linker keeps resource names in DXIL reflection even when the -Qstrip_reflect is used. Compiling lib_6_3 targets also leaves the resource names in too, so there doesn't appear to be any way to remove them.

Steps to Reproduce Run this:

void ReflStripBugTest(IDxcCompiler3* aCompiler, IDxcLinker* aLinker)
{
	const char* sourceBlob =
		"Texture2D<uint> texResource : register(t900);\n"
		"RWTexture2D<uint> rwTexResource[] : register(u0, space2400);\n"
		"[numthreads(8, 8, 1)]\n"
		"void main(uint3 dtid : SV_DispatchThreadID, uint3 gtid : SV_GroupThreadID, uint3 gid : SV_GroupID, uint gindex : SV_GroupIndex)\n"
		"{\n"
		"    rwTexResource[0][dtid.xy] = texResource.Load(dtid.xyz);\n"
		"}\n";

	DxcBuffer sourceBuffer;
	sourceBuffer.Encoding = DXC_CP_ACP;
	sourceBuffer.Ptr = sourceBlob;
	sourceBuffer.Size = strlen(sourceBlob);

	const wchar_t* compileArgs[] = {
		L"-O3",
		L"-T",
		L"lib_6_3",
		L"-Qstrip_reflect",
	};

	IDxcResult* result;

	aCompiler->Compile(&sourceBuffer, compileArgs, sizeof(compileArgs) / sizeof(compileArgs[0]), nullptr, IID_PPV_ARGS(&result));

	IDxcBlob* compiledBlob = nullptr;
	result->GetResult(&compiledBlob);

	const wchar_t* libName = L"MyLibrary";
	aLinker->RegisterLibrary(libName, compiledBlob);

	const wchar_t* linkArgs[] = {
		L"-O3",
		L"-Qstrip_reflect",
	};

	IDxcOperationResult* linkResult = nullptr;
	aLinker->Link(L"main", L"cs_6_3", &libName, 1, linkArgs, sizeof(linkArgs) / sizeof(linkArgs[0]), &linkResult);

	IDxcBlob* linkedBlob = nullptr;
	linkResult->GetResult(&linkedBlob);

	const void* linkedData = linkedBlob->GetBufferPointer();
	size_t linkedDataSize = linkedBlob->GetBufferSize();

	IDxcResult* disasmResult = nullptr;

	DxcBuffer linkedBuffer;
	linkedBuffer.Encoding = DXC_CP_ACP;
	linkedBuffer.Ptr = linkedBlob->GetBufferPointer();
	linkedBuffer.Size = linkedBlob->GetBufferSize();
	aCompiler->Disassemble(&linkedBuffer, IID_PPV_ARGS(&disasmResult));

	IDxcBlob* disasmBlob = nullptr;
	disasmResult->GetResult(&disasmBlob);

	const char* disasmText = static_cast<const char*>(disasmBlob->GetBufferPointer());

	puts(disasmText);
}

Actual Behavior Disassembly contains the resource names in the metadata.
