   `ParseToDate` is a `RuntimeReplaceable` expression. The `ReplaceExpressions` 
rule (Finish Analysis batch) substitutes it with its `replacement` before 
physical planning, so the class never appears in a physical plan and Comet's 
expression serde never sees it. Registering a `CometExpressionSerde` for it 
would be dead code.
   
   Its replacement is `Cast(GetTimestamp(...), DateType)` when a format is 
given, and a plain `Cast(child, DateType)` otherwise. Comet already handles 
both `Cast` and `GetTimestamp` (`CometGetTimestamp`), so `to_date` already runs 
inside Comet today without a serde for this class.
   
   Closing as not actionable as specified.
