I would question the assumption that this is “not suitable for production use” means “everything is broken and we're way behind” rather than, say, “we are being extremely conservative because our customers will expect support as soon as we say it's production ready and we need to test every upgrade scenario for our large number of existing customers”. The AWS-managed ElasticSearch seems to be pretty popular and I would expect them to be as conservative about new offerings as they are with, say, RDS.
