Well, there are things we still don't allow in one binary, and I suspect it would be nasty on ARM too, such as widely different core arch (which in ARM land would translate into widely different ARM architecture version). But yeah, we can pretty much make giant defconfigs. They are not very useful tho. In the embedded world, size constraints are quite strong and so you really need to be able to target only the subset of things you want for some types of devices. Of course, for things like ARM netbooks, it would be nice to have one giant defconfig that boots them all, and that's probably an achievable goal if the variants between bootloaders can be sorted out.
