approved but not a fan of commenting out code, at all
please just delete instead, and leave a comment with a link to a github commit containing the commments

Or write todos

[danwt]

can we just delete instead of commenting
or if commenting out, needs a TODO: and an explanation

[danwt]

why dont we do it in this PR?

@mtsitrin e2e tests fails. possibly due to genesis changes.

[omritoptix]

@mtsitrin this change breaks the relayer. when trying to create an ibc connection, getting the following error (while trying to query for the unbonding period though it's defined in the genesis). I assume we need to route the staking grpc queries to the governors module:

Error: error creating clients: failed to create client on dst chain{dymension_100-1}: failed to get trusting period for chain{rollappevm_9988-1}: failed to query unbonding period from ccvconsumer, staking & fallback : failed to make ccvconsumer params request: rpc error: code = Unknown desc = ccvconsumer: unknown subspace: unknown request: failed to make staking params request: rpc error: code = Unknown desc = staking: unknown subspace: unknown request : rpc error: code = Unknown desc = unknown query path: unknown request

This is one of the relevant parts from the relayer code:

func (cc *PenumbraProvider) QueryStakingParams(ctx context.Context) (*stakingtypes.Params, error) {
    res, err := stakingtypes.NewQueryClient(cc).Params(ctx, &stakingtypes.QueryParamsRequest{})
    if err != nil {
        return nil, err
    }
    return &res.Params, nil
}

In order to reproduce simply follow the extended readme until the point of setup_ibc.sh which will fail.

closing for now until we decided the direction with that
