I don't really see a use-case for overriding wherever the environment at the user-level actually. At the board level, for redundancy or transition, yes, definitely, but we can already do that.
If the feature is available, use cases will spring into mind.
Assume you have a eMMC based system which can also boot from other storage (say, SDCard), and you want to write the current content of the eMMC environment to the alternative boot device.
Yes, there are usually alternative approaches to perform similar actions, but an easy way to save lsewhere might be handy, especially if it comes at low cost.
Right, but that would bring a much more significant rework as to how the environments are handled than just the changes that are being discussed here. At the moment, the environment can only be stored on one device for each "types" (one raw MMC, one MTD partition, etc). The redundancy allows you to duplicate it, but you won't be able to store on just one instance of your choosing at the moment.
