I think it's a quite good change after all. I think I know how it happened:
1) wizards cannot use armor, but... see 2
2) wizards compensate with Mage Armor or similar spells
3) Mage Armor becomes a must, the majority of 3e wizard have it
4) if nearly everyone has it... 4e turns Mage Armor into a feat
5) now the feat is a must, so why not just let them wear armor? the effect is the same, so let's just make it so that the feat allows you to not bother about buying armors
