I just looked into IBC and various "messaging/bridge" things, and honestly, crossing one chain, you don't trust just one line: the source chain itself shouldn't rollback, the light client/validator set shouldn't cause issues, relays shouldn't randomly drop packets, and the contracts/modules on the destination chain shouldn't be written to explode... If any link in the chain loosens, it can all end up as "I thought the funds had arrived." Sometimes people criticize bridges for being unsafe, but actually they're just trusting a bunch of components as if clicking a button. By the way, thinking about blockchain games, when the economy crashes, studios run away + inflation kicks in, and token prices spiral up, the more frequently cross-chain assets are moved back and forth, the more it looks like an accelerator... I personally still prefer low frequency, I'll sleep first and decide whether to tinker later.
