Wizards are supposed to get this feat at lvl 1 for free, but don't-so... I guess you can somehow control that?
I believe the issue with cantrips is for wizards who were created prior to the release, though admittedly I haven't tried creating a wizard yet to see if they get them automatically at creation now that the hak is in play
edit: Nope nope nope, I was completely wrong. Wizards get scribe scroll on creation but it doesn't come in to play because, as you said, it doesn't exist in the mod
Additionally I was completely wrong about the cantrips.
