Much of that log is just issues with one implementation, which would indicate that the Safari team is either underfunded (time/talent/money wise) or incompetent to break a working/"feature complete" system, multiple times. Not really an issue with the spec as written.

As for transactions.... Yeah I'll admit they suck hard, and can be a pain to remember the quirks of them, as well as dealing with the callbacks.

Quotas and Private mode... Those same issues would apply to webSQL, and webSQL didn't have a way to delete the database to clear it up.
