Although we are in the process of phasing out the RSS aggregator, it is still there in 6.2.x as a consquence of the dependency on magnolia-categorization-rss-integration. But because the dependency isn't explicit, the release automation doesn't pick up on it (see MGNLMGMT-13). The goal of this ticket is to add an explicit dependency so that releases that include rssaggregator work flawlessly.
