Wallets need to be online as little as possible, nodes need to online as much as possible. However, a full node background process could also be running if the wallet is not open itself. Ffor example - by running as a system service. Bitcoin Core's own wallet is also moving to SPV, so this means a general solution is needed to get people to run a node when the wallet is not running. Maybe the node shouldn't be controlled from the wallet at all, it could be a 'node control' user interface on its own (this is what -disablewallet does currently). In this case, there is no need for packaging it with a wallet The only drawback would be that initially, people wouldn't know why or when to install this, hence my suggestion to pack it with wallets...
