It's not required in Germany either. The data protection law allows to "lock" data instead of really deleting it from all devices. And IMO that's the only sane solution to deletion requests.
Otherwise, any kind of backups would be unlawful for a company.

Though this requirement is moot even in Germany, as it is impossible for you to verify such a deletion.
(Whether German data protection law applies in Google's datacenters is a wholy different story though.)
