Don't know about the OP, but there are some rarer cases, like dynamodb, where more indexes means more $, you can avoid creating a timestamp column & new index by having a sortable id column.

But even without the need to sort by id, one of the advantage is that sequential ids makes it easier for databases to fetch data, as data stored ends up being more sequential in disk as well.
