uEnv.txt and boot.scr aren't the same thing. uEnv.txt is the U-Boot environment usually on a fat partition.
I have no idea why it'd be limited to FAT; it's just a file...
boot.scr is loaded by a readily loaded environment... You either predefined your environment and boot from it or you're using values from that environment. I wouldn't use uEnv.txt to replace a boot.scr on any system..
I'd view uEnv.txt as simply a different way of writing a boot script. "env import" has a -d option which appears to merge the loaded environment into the current environment, rather than completely replacing the environment. I could easily imagine loading uEnv.txt, expecting it to define some specific variable/macro containing the subsequent boot commands, and then "run"ing that variable.
