I went over there to see what the debate was about, and I still can't see the other side of this. It appears there is some concern about cheating in the game - both for friendly games and tourneys - with hidden enchantments being cast on illegal targets, so they have decided that because it's easier to just let this happen that enchantments do not follow the normal rules of casting and targeting.
I gotta say, I am not sure how they get to that conclusion or why there are multiple people claiming confusion at the rules for this. Enchants clearly follow all rules of casting a spell, then after they resolve the Enchantment rules take over for reveals and such. *shrug* I am at a loss to understand their position or how this is "inconsistent" with the rules of casting spells as is claimed in that thread.
