Please try to look over the rim of your plate. Even if you make
"saveenv" work with some magic, your end users may have a zillion
other ideas why they want to access the flash - for example, to store
a copy of the environment created using "env export", or to reload
such a saved profile using "env import". Why should their needs be
ignored?

Sure. Delete the env var, switch mode to flash access, run saveenv,
run reset.
