As someone who is involved in the ecosystem and maintains some open-source projects based on ElasticSearch, I am similarly curious about the move to not build upon existing projects (there could be a good reason, but haven't heard it yet).

Why wasn't ElastAlert used / built upon for alerting? https://github.com/yelp/elastalert

Or why wasn't ElasticSearch SQL used / built upon for SQL? https://github.com/NLPchina/elasticsearch-sql

Or why wasn't SearchGuard used / built upon for Security? https://github.com/floragunncom/search-guard
