Probably YouTube went for MySQL because that was a standard part of the LAMP stack — in the absence of any compelling factors, just about any Web developer in the mid-2000s would have chosen MySQL — and Google didn't see the benefit to switching.

Probably the testing relational storage for AppEngine?

No, it's used as the backing store in many production applications. Some tasks lend themselves to distributed non-SQL datastores, other tasks work better with a traditional database architecture. MySQL is used for the latter.

Does any know if these changes went into Percona Server? I can save the lookup.
