Summary of Bug

Keeper constructors still take paramtypes.Subspace as a parameter (e.g. https://github.com/cosmos/ibc-go/blob/59e42c6/modules/core/keeper/keeper.go#L43). This requires users to include x/params to pass in an initialized Subspace.

Instead, these constructors should take in an interface like cosmos-sdk modules do (e.g. https://pkg.go.dev/github.com/cosmos/cosmos-sdk@v0.47.5/x/auth#NewAppModule). This allows users to pass in nil and not have to include x/param types.

Expected Behaviour

See above.
