I am fine with that and build systems (buildroot and OpenWrt at least) typically offer a way to produce a device specific image that will contain a single DTB fit for the target device.
What we would be optimizing for would be build time vs. coverage, as a maintainer I favor coverage as it allows me to build everyone in one sweep. We could make the building of the 63138 conditional upon BCMBCA_CORTEXA9 if that bothers you. -- Florian
