CloudSQL overall is a great product, but not having a public roadmap or communicating at all with their customers is pretty rotten and you really can't trust them because of that. I would recommend anyone considering putting things on CloudSQL stay vigilant - this may be the last update for 3yrs (like the last release) so don't get too attached.
We tried for months to get an answer out of somebody at Google about this and could not get a solid response - no clue if they were working on it at all, if the product had anyone working on it, or if it was even going to stay around. This caused us (and I'm sure many others, based on the huge threads on their bug tracker) to move off of CloudSQL for greener pastures. These "surprise" Apple-style announcements don't make anything better for the people who actually have to plan their infrastructure out.
