The same thing applies here as well. The only key difference is user
convenience in two ways: (a) when there are a lot of columns, say 100
columns, and user would like to send all data except 2 columns, (b)
adding new columns to table would require users to again run the DDL
to change the column list.
These are primarily the two pain points YeXiu wants us to solve.
