For a fully custom closed embedded system, nothing.

But as we move towards more generic kernels that support more
environments, ubldr has the ability to:
  * Load the kernel from UFS (which in turn means that end users can use =
buildkernel/installkernel to update the kernel)
  * Load the device tree separately from the kernel.
  * Interactively edit the device tree
  * Preload specific modules
  * Script the boot process (the i386 interactive boot menu is a Forth =
script that runs on the stock loader; ubldr has the same ability)
