Review Comment:
   I think this is a little hard for me since everything is in the try catch 
here, maybe instead we keep the older pattern of
   ```
   if (expr != null) {
     try {
      bind
      pushdown to iceberg
      If (not fully pushable) {
        add to spark
      }
     } catch {
       leave for spark
     }
   } else {
     leave for spark
   }
   ```
   
   But i'm pretty sure this is correct either way
