Review Comment:
I’m thinking whether we should decouple the handling of drop column
separately instead of turning on “schema reconciliation” by default, e.g., we
should still allow new columns to be added instead of dropping them to favor
table’s schema by default, while properly handling the column drop (maybe a
different config?).
