Shared chests in houses don’t make sense. A guest can use the shared chest while they are in front of it, but they can’t use the resources remotely at crafting stations or shops like the owner can. This isn’t the case with chests in the Rookery, and there should be an option to have the same functionality on house chests.
Some of us live together and don’t want separate houses or storage, but instead want to pool all our resources. Right now, that is inconvenient for guest players.
Also I agree with other posts that there is almost no point to housing right now except to house chests.
