Can you add a little more help detail on this? Also I suspect we
should have CONFIG_ENV as well, to enable the actual environment
(independent of where it is stored).

Also, can you migrate the existing configs with moveconfig? That would
be a big step forward and may inspire me to move it to linker lists.
