I wrote a blog about this and you can check it out here.
Notches in a Shimano/Sram freehub body
It's not a big deal until the free cogs are stuck and you need a chain whip to get them off for maintenance... and your shifts are bad because the chain can't engage the next cog. Didn't have this problem with Boyd hubs, rather with PowerTap G3 hubs. Had to switch over the Campagnolo 11 speed to stop the biting.
