I don’t understand what happens inside heads of Apple’s developers (someone please stop paying their wages). The Mach-O format already has several structures like “Indirect Symbols” (have all the necessary data for symbol binding), “Local Relocations” (that work like rebases), “External Relocations” (that work like relocations) - all these structures live in dysymtab_command, also it has “Rebases” and “Bindings” (live in dyld_info_command). And now they gave birth to NEW structures that DO THE SAME THINGS!
