LGTM! config changes are nice.

For the IBC param stuff, what was the problem here? You noted set default IBC params until app wiring is fully supported, can you add some context here?

We are currently registering IBC modules manually in app/ibc.go, and the default params were not set, causing a panic on ExportGenesis.
