"Other than having to download and burn two things" is a rather big deal to me. First it adds extra work actually get two

A multi-file image is supposed to work, too. I never tested this, though.
Don't like this idea, its not a runtime/kernel load feature, IMHO. What devices that is supported should be provided by firmware.
Secondly, now you have to reserve a DTB flash partion so you have somewhere to store it and that is a waste of space. Then you have to add even more args to the boot command to
tell uboot where
to find it.
All this can be dealt with by using a multi-file image.
Can you add/modify OF items in a multi-file image?
To me this new OF seems like a nice feature for developing new stuff, but once you are done and ready to ship it only complicates things for boards that don't need this new flexibility.
I disagree here.
Clearly, but you don't say why. You are saying that a multi-file image might work but that won't work in a system where you need different OF trees. I am supposed to supply X multi-file images, one for each board where only the DTB differ?
