Since the dawn of time for the Allwinner support in mainline U-Boot we store the environment to the SD card and write directly at 544KB from the beginning of the device. This leads to problems when the U-Boot proper image grows beyond 504KB and eventually overlaps. With one release of having the environment preferably in a FAT partition, let's now turn off the MMC variant fallback, so we get back all the space we need to implement features. In case someone desperately needs to turn direct MMC environment back on, let's move that to 896KB (128K below 1MB), so that we won't be easily limited anymore.

I'd go even further and remove it for everyone.

However, I'm not sure why that would be needed. I would rather keep the old value to have an easy fallback to the old environment, given that you disable a few things afterwards.
