737-100/200/300/400/500 Would fail current certification standards?

Am I reading the last section of this NTSB report correctly. Does that mean that the 300/400/500 are only certified to the old standard and based on the physical efforts required by the crew it would fail current certification?

"The design of the pitch control system on the 737-300/-400/-500 airplanes is essentially unchanged from the 737-100/-200 airplanes.

When the 737-100/-200 airplanes were certified, the FARs did not specifically require consideration of a single point failure mode (such as a single PCU rate jam) as long as the failure mode was considered extremely remote. The FARs have been modified since then..."

Still, a pharmacist friend of mine said if they discovered Aspirin today it would never get approved :-)
