x64 RPM is in 1.2 on Nov 9. ARM RPM is going to be in 1.3. As @oscark noted, it’s on the road map.
A lot of this was affected by needing to fork the clients and produce an output plugin for Logstash (see: OpenSearch Roadmap & Release Update). It’s nothing technical, it’s just a bottleneck in capacity. Good news is the team is automating at they go along so it should pay off later with the ability more rapidly release.
But I do hear you both - RPM and DEB are super vital to serious use for a lot of folks.
