Why should Wizards get every single type of summons? This isn't 3E any more. Wizards are scoped down to be kind of sane now.
They shouldn't, but they should get summon monster, a spell that they've had forever. Saying "wizard's just don't summon monsters any more" is like saying "wizards just don't fire magic missiles any more". It's removing the ability for no real reason.
Now if the argument is that summoning bogs down the game and is wildly unbalanced... then maybe make some better rules for doing it, rather than saying "everyone gets summon spells except wizards".
