Architecture question about implementaions with/without RCA


Please explain me why GitHub - opendistro-for-elasticsearch/performance-analyzer: 📈 OpenDistro for Elasticsearch Performance Analyzer and GitHub - opendistro-for-elasticsearch/performance-analyzer-rca: The Performance Analyzer RCA is a framework that builds on the Performance Analyzer engine to support root cause analysis (RCA) of performance and reliability problems for Elasticsearch instances. are different repositories and even different directories in plugin archive (but with similar content like startup scripts, config, log configuration and so)?

Maybe pure plugin archive without duplicates + standalone daemon archive (to run in separate sidecar container) will be better solution or some roadmap for more clean implementation is already exists?

Maybe such question better to discuss elsewhere (in GitHub bugtracker for example)?
