FIXME: This function is problematic, because despite always returning a valid Carrier,
it has an optional __SENTRY__ property, which then in turn requires us to always perform an unnecessary check
at the call-site. We always access the carrier through this function, so we can guarantee that __SENTRY__ is there.
Returns the global shim registry.
