Is there any reason why FC chests hold so little?

We can have 512 players in an FC, but we only have 5 FC Chest tabs at level 30, and each tab only has 50 spaces.

Can the rank 30 FC get a perk that increases FC chest space to at least 100 spaces per tab? I daresay it should be 200 spaces per tab for those FCs who do a lot of crafting and gathering. As it stands, I'm having to use 8 different retainers to hold items that I'd like to hold onto in case my FC members need something crafted.
