There's also a recent proposal to include an IBC packet routing feature from u/jackzampolin that should go onto the hub soon: https://github.com/cosmos/governance/pull/46. This would make it easier to use the Hub as a router, on of the strongest and earliest uses for the Cosmos Hub. As the author of the go relayer and a relayer himself, Jack knows that it's easier for relayers to operate between one network and the hub at a time, compared to running relayers between every single network. Today there are only a handful of live networks using IBC so the latter scenario is still possible. However it may be important to set the precedent that all IBC packet routing should go through the hub to ensure it continues to be the case as the number of IBC connected networks grows. This new feature allows a single IBC transaction to result in multiple hops through the Hub to a destination chain.

This is an explicit point of the Gravity bridge design. Described here in the proposal.
