I know, it's frustrating. Extended Spell is useful on a handful of spells (Aid, Aura of Vitality, Healing Spirit, Mage Armor, Conjure Animals, Foresight) but many of those spells aren't on the sorcerer spell list, and there are so many things you'd expect to be able to do with it that just don't work, and it isn't clear why.

Extended Shield should be a thing but it isn't, unless the DM overrules the PHB.
