Agreed - dropping WebSQL for much weaker inferior IndexDB made no sense to me. Instead of going backwards, there should be a choice for persistent data - Text cookies or Simple KV Doc store or Relational db. I don't buy the dogmatic arguments against SQLite which is Open Source software of the highest quality - even if a major bug is discovered, there is always the option to disable it, anyway surely surely the likes of Google would have every incentive to help fix it quickly.
