@kaknikhil I checked the 1.11 -> 1.12 scenario. The tool is missing
the`tree_train` and `forest_train` entries. The change seems to be the removal
of `surrogate_params` and the addition of `null_handling_params`. Since both of
them are `text` type, it does not get picked up by the `diff_udf.sql` script. ---
