Why doesn't the recipe book work anymore with JEI/REI installed?

With these mods installed, the vanilla recipe book search system is disabled to speed up world join time and reduce memory usage. This is because JEI/REI implement largely equivalent functionality, and the vast majority of modded players do not use the vanilla recipe book at all. If you do not like this change, disable mixin.perf.blast_search_trees to restore original behavior.
