In my "build everything" tree, changing a type in qapi/common.json triggers a recompile of some 3600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h).
One common dependency is QapiErrorClass: it's used only in in qapi/error.h, which uses nothing else, and is widely included. Move QapiErrorClass from common.json to new error.json. Touching common.json now recompiles only some 2900 objects.
