I think the reason for the inability to do multiple upgrades on sub commanders is that it stops you from accidentally killing your economy by telling too many sub commanders to upgrade at once
other than the inability to cancel upgrades on non-mobile units, I love the game, and thus far I have had no issues that I wasn't able to get resolved pretty fast
