   > make_interval was considered but left for a follow-up: its output type is 
CalendarIntervalType, which Comet's columnar layer does not yet support (the 
dispatcher reports unsupported output type CalendarIntervalType and falls 
back). It can be enabled once CalendarIntervalType support lands 
(https://github.com/apache/datafusion-comet/pull/4898).
   
   I think you're https://github.com/apache/datafusion-comet/issues/3099 refer 
to this? I saw the native `SparkMakeInterval` implementation is ready and 
registered as comet udf, what we need to do add a new catalyst mapping 
`classOf[MakeInterval] -> CometMakeInterval` and `CometMakeInterval` scala 
implementation to convert expr to `make_interval` proto?
