I am pretty sure that Microsoft's objection to this will be achievement cheating. There are several achievements that can be had with a single console command.
I think this too and posted in another similar thread:
"If you can use the console commands to alter the game to enable you to gain XBL achievements without doing them in game, then this is why they are not allowed to enable the console in the 360 version. MS would also be within their T&Cs to ban any live accounts they detected doing this (to obtain ach points). Whether they would ban people who just enabled the console (without using the console to obtain easy achievement points) if they could detect them, is another matter.
I would have thought that Beth could have gotten around this by deactivating achievement gains when the console is enabled, but this would have been another thing they would have had to cram in before 11.11.11."
