I don't think a distro should need to know the DTB filename at all.
Rather, the/a bootloader should know which platform it's running on, and
provide a variable/... to the boot script/... that defines the DTB
filename. That would completely remove all the knowledge of DTB
filenames from distros.

At some point the distro has to install a dtb into some cannonical
place so the bootloader can find it..

Are you thinking that distros will have to ship a /boot/dtbs/*.dtb
with every dtb from the kernel build?

What happens when you install two different versions of the kernel?

What about boot schemes that can load a kernel version dependent dtb?

I've said this before - I really think the kernel community will do
itself a big favor if it encourages boot schemes that can handle a
kernel version dependent dtb, rather that design schemes that
absolutely can't allow for that.
