It was originally intended for temporarily testing a modified version
of a package, which you commit by generating patches from it. But I
expect that in companies it will indeed be mainly used for the application.

Actually, BR2_TARGET_UBOOT_CUSTOM_GIT and
BR2_TARGET_UBOOT_CUSTOM_TARBALL exist for exactly this purpose. Of
course, there's no equivalent for xloader, but you should start using
U-Boot SPL anyway :-)

Sounds like a good idea to me.
