I will post the DDL with exact fields we are going to save to answer
this question.

Maybe just make them be an empty string. Appending an empty string
won't change the hash because it doesn't change anything. For example,
we create a new field x, make it nullable, if it's NULL then when
we're validating the old records that don't have this field just treat
it as an empty string, it won't change the hash, so it's backward
compatible.

I agree with you.
