First off, adapting religion to secular laws is not how that works. There’s the separation of church an state and the state should have no say in any religion. The country was based on religious freedom and escaping what the English kings were trying to do to Christianity in their realms (controlling religion).

But second you shouldn’t take that way since you don’t seem to grasp the role reconciliation has for Catholics and Orthodox (and others). It’s a sacrament (or sacred mystery for Orthodox). That’s dogma and the practice/form is in large part a matter of unchangeable doctrine. That kind of doctrine never gets changed, ever, and never has. It’s an essential part of Catholics’ beliefs. Parts of format are just regular teaching which can get changed, but that’s not a matter of interpretation, it’s a matter of practice (in this case canon law) guided by the foundatinal dogma and unchanging doctrine. The seal of confessing is so fundamental, so sacred that there have been numerous martyrs whose status comes from having been willing to die rather than break it. It’s would be less grave to lie about believing in Christ to save your life than to break the seal (and most martyrs died for refusing to reject their faith when Christianity was prohibited).
