I agree with you. Superceded is the wrong word. Fulfilled is the correct word.
Jesus didn't annul the law, He fulfilled it. The sentence of death for sin was not abrogated, it was PAID by Jesus. Certain aspects of the law, including the kosher laws were set up as a sign to separate Israel from the other nations. They never applied to the gentile nations and when salvation was extended to the Gentiles, there was no reason to extend these laws.
The basic law to "love others and walk humbly before your God" is still in effect. But noone was ever saved by the law, except to the extent that knowledge of the law made us aware of sin. And that knowledge led us to repent before the Lord who redeemed us.
