There is also the fact that all of the platforms U-Boot runs
on appear to be very simple ones.  No complicated
SPD base memory initialization, etc.

LinuxBIOS supports much more complicated hardware.

That is the other reason for the design skew.  If you can write
proper memory initialization code in a day.  You can put it in
your bootloader.  If it takes a week or two, separating board
initialization and your bootloader makes a lot more sense.
