nit: I'd also static_assert() on the sizes.

static_assert(content::PushRegistrationStatus::PUSH_REGISTRATION_STATUS_LAST ==
                  content::mojom::PushRegistrationStatus::LAST,
              "PushRegistrationStatus enums must match");

(etc)

Oh, We did discuss on this before. Sorry I forgot to add it:(
And we need a static_cast<> before comparing, like below:
static_assert(content::PushRegistrationStatus::PUSH_REGISTRATION_STATUS_LAST 
                  == static_cast<content::PushRegistrationStatus(
                        content::mojom::PushRegistrationStatus::LAST),
              "PushRegistrationStatus enums must match");
to pass compiling.
Thanks reminding me!
