Were indexes always included in sqlt_data_* tables?

Well, here is a post where I was clearly positive that they were not there by default in 7.9.

The performance issues come in if no indexes have been added to the tables (they aren't there by default in 7.9) and so the database engine will have to trudge through all of that data to gather the information being requested, and that can kill a server that doesn't have enough memory available
