Funny thing, there were plenty of folks who supported the one, and not the other. They disagreed with you.
There were plenty of folks who disagreed about individual amendments. To my knowledge, none of them therefore thought it was 10 discrete, unrelated documents. Thoughts do not occur in isolated containers. If one wants to know what original intent was, one must examine the intellectual anticedents of the event. Your position--that because we don't know what happened in secret meetings of a special committee of the congress, therefore the original intent was accomodation--is one mighty feeble excuse for an argument.
