U-Boot varies massively from board to board and *doesn't* provide
standard interfaces. Those are major problems when you're trying to
give a consistent user experience for booting. On the various small
embedded platforms where people are recommending to replace U-Boot,
it's often (but not always) easy to replace it if you make a mistake
(swap SD card, etc.).
UEFI is explicitly specified to give standard interfaces with
reliable, known behaviour across different implementations. It's often
*not* easily user-replaceable (just like on x86 servers) and we should
not be buggering with it once it works.
