+1. @grafana/data is not supported in grafana 5.x and 6.2. The workaround is
+the module `./libs/grafana/events` that include copy-pasted events
+from @grafana/data and app/core from grafana sources.
+
+2. Newly Grafana versions flood Console with
+"Usage strings as events is deprecated ..." messages.
+This module has a function to detect if Grafana’s Emitter support AppEvent style event ids.
