And hold up. There are specific alignments that that list mentioned shouldn't be added, SPECIFICALLY Chaos roles, and Mafia Killing roles. Chaos roles? Eh. But the issue is that BMG looks down upon them. Maf Killing roles, however, cause Mafia to be unbalanced.

Both have clear reason to not have roles added to them, as they would be rejected heavily. However, the other alignments are completely free right now.
