@iuhilnehc-ynos overall lgtm, i still think we should not use DDS, how about replacing those into RMW implementation?

// Content filter topic not supported (or not enabled as some failed cases) on rmw
// implementation.
// TODO(iuhilnehc-ynos): enable rcl content filter fallback with an environment variable
// (e.g. FORCE_COMMON_CONTENT_FILTER) regardless of whether cft is enabled on DDS.

bool is_cft_support =

std::string(rmw_get_implementation_identifier()).find("rmw_fastrtps_cpp") == 0);
// rcl CFT will be the fallback if rmw CFT is unsupported on DDS

@fujitatomoya

You're right. we should not let users know something about DDS information in RCL layer, even if the DDS characters.
