The assumption that the Canons of Dort requires infralapsarianism or precludes supralapsarianism seems to lack historical perspective. It seems similar to the assumption that the Canons of Dort and the Westminster Confession excludes Hypothetical Universalism (of the non-Amyraldian variety).
For one thing, the Canons were endorsed by supralapsarians such as Francis Gomarus. Also, it is unlikely that they intended to rule the views of men like William Perkins et al. out of bounds, as Dort was meant to be broad enough to unite those who were generally orthodox, despite some minor differences, in opposition to the Remonstrant Arminians.
Even if other confessions require infralapsarianism, I prefer to stick with the Westminster Standards, which are the most careful and circumspect expression of Reformed orthodoxy.
