In 3E, they didn't have to. Players could do summons and illusions and create undead and all kinds of options without waiting for splat books.
Except of course it meant that wizards/clerics did everything.
Every school of magic was something the wizard could access, and future classes couldn't really do anything a wizard couldn't already do. So psionic creatures, masters of the mind, were basically using variations of enchantment and illussion.
They put an entire set of illussion based powers up immediately.
Summoning and creation of undead [and leadership, and all similar powers] were all somthing that was quite unbalanced. Spend a turn casting a spell, get another person added to the party ... the long term undead creation powers and leadership being even crazier.
They took a small period of time, but they've already reintroduced short term summoning in the game [through items instead of spells, although spells have their own conjuration effects].
