Sorry, but I don't follow the new features of u-boot that closely.

Is it already possible to save an exported environment as (text-)file to 
some storage? Such wasn't possible when I've implemented that -r for 
"env import" and it doesn't make much sense if an exported environment 
never reaches users.

Another problem would be to decide in which format to save the 
environment. Same magic (e.g. an env var set by "env import") would be 
necessary to decided in which format to save the environment.
