Why is it irrelevant?

Leather armor proficiency has no prerequisites?

Cloth armor isn't irrelevant unless all you care about is AC. There are some useful enchantments that can only be applied to cloth.

This.

Plus, it costs a feat to become proficient in leather armor, even if it has no prerequisites. The player might want something else for that feat. Leather armor is thus a choice that's open to the player, not something that's mandatory.

Agreed - even with 6 feats in the heroic tier, every character I've planned has wanted more feats

For a specific wizard build I'd spend the feat; but in the general case? Nah.

Also, most NPCs won't have feats, so even if there's never a PC wizard in the campaign without leather proficiency, there will still be wizards in the world running around in cloth.
