You can do that, my intention was not to step on @t00thpick1's toes, you'd have to ask him whether or not you can remove that case. It's fine with me, I'm not quite sure what the intention of ac1a2d0 was, I can't figure out how to get back to the PR it came from to see all the details.

That said, it seems like the main fix in that change was to not break out of the loop when adding enchantments for a book. Remove the break was perhaps all that was necessary, but unfortunately the additional refactoring seems to have caused some unintended side-effects.
