Brainstorm interfaces for "UUID Delta tables" / "primary key Delta tables"

[MrPowers]

There is a good argument for creating Delta tables that have a uuid column by default.

Yes, a uuid column requires a bit of overhead, but should make it easier to perform other operations on the Delta table down the road. A UUID column makes it a lot easier to deduplicate the Delta table down the road for example.

It could be cool to create an interface that makes it easier to create, append to, and maintain tables with a primary key / unique identifier column. Let's brainstorm!
