We maybe[1] should, but we are not. AFAIK there's no relational query engine for IndexedDB. Also, there are a lot more people who can get things done with SQL

We maybe[1] should, but we are not. AFAIK there's no relational query engine for IndexedDB. Also, there are a lot more people who can get things done with SQL than using indexed KV-stores. KV stores tending to have horrible APIs doesn't help the situation. [1] E.g. SQLite started with a gdbm backend, but later rolled their own because of limitations caused by it.
