FKismetCompilerContext::CreateUserDefinedLocalVariableForFunction() does not copy the metadata from the source FBPVariableDescription entry. Class variables work because there is code for that in FKismetCompilerContext::CreateClassVariablesFromBlueprint().
Currently not exposed by default, but if a details customization is created to allow a project's users to set metadata on local variables via FBlueprintEditorUtils::SetBlueprintVariableMetaData(), that data will not be copied to the generated property at compile time.
