The usefulness is that it explains _why_ it's failing. The reason why it can is because this method uses a hack to do batch inserts. The proper fix is to use the newer syntax, but staying with this hack means that the user will need to dive into this code _and_ track down the SQLite hack to figure out why it's failing. I'm sure there are better fixes by people who know the codebase, but not doing anything is the worst option, IMHO.
