There are a few non-IBC changes that affect other modules/pkgs. The most relevant is the following check:

	// x/<module>/keeper/keeper.go

	// set KeyTable if it has not already been set
	if !paramspace.HasKeyTable() {
		paramspace = paramspace.WithKeyTable(types.ParamKeyTable())
	}

Should we leave this check? @alexanderbez @cwgoes @jackzampolin @AdityaSripal ?

[jackzampolin]

I think we can kill that one @fedekunze
