It'd be the right time because though IDB usage is picking up, it's still
relatively low. Optimally this change would have been made a few months or
years ago, but now is better than later.

We'd be ok with changing this, our unprefixedness notwithstanding. I think
the pain it would save developers down the road would make up for the
immediate pain it would cause to both vendors and developers. But that's
just a judgment call, I'm relying on intuition and obviously have no data
about what the future will hold.

To balance the concerns of open with complicated semantics and
backward-compatibility, I propose that we add two methods to IDBFactory:
openOrFail and openOrBlock.  Most introductory IDB tutorials and examples
would steer developers towards openOrFail.  The current open method would
be an alias for openOrBlock.  That open's documentation would be
"[deprecated] alias for openOrBlock" should give developers some pause
about using it just because it has the simplest name.

At least the Amazon cloud reader uses IndexedDB. I've started
