The main problem is tracking who puts items IN the vault. Storage space is one of the most precious resources in the game. Newbs can and do waste this space by putting low value and hard to track items into the vault.
Maybe if you don't recruit your guild does not have this problem. But we have tried posting storage guidelines in our guild forums and even the MOTD, to no avail. Cleaning up the resulting mess just leads to extra work for the HOs. A log would allow us to identify and educate clueless trash stashers.
An alternative suggestion would be disallow member adds to the vault. An even better idea (but more dev work) would be to allow the GL to customize vault access both IN and OUT separately by rank.
