1.12 recipes that aren't controlled by CraftingManager

[Jay Avery]

I'm starting to update my mod to 1.12 and recipes are obviously one of the biggest changes. My mod has a bunch of different crafting devices which each have their own recipes (none of them use the vanilla CraftingManager). Is there any way to put my own recipes in tabs of the vanilla recipe book and associate them with the correct crafting device to function like other vanilla recipes? I've looked through the recipe book code and it looks pretty hardcoded to vanilla inventory and crafting table recipes. I'm a bit irritated about the recipe book because it seems like a somewhat less-functional and less-adaptive version of JEI, which I just finished incorporating into my mod! Is Forge likely to make the recipe book any easier to add recipe categories to in future updates (more like JEI)? Or shall I just resign myself to ignoring the recipe book entirely and telling people to use JEI if they need recipe help?  Sorry I know this question is a bit vague. I guess I just want input on how much I should worry about incorporating or ignoring the 1.12 recipe book to my recipe system.
