Cluster Initialization is missing for custom `conf.join`

I have a setup for CockroachDB using multiple Kubernetes Cluster. Since the automatic `join` list only contains the services from the local cluster but not the other cluster, I used a custom `conf.join` list with the services from both clusters. But unfortunately the `job.init` to initialize the cluster is not running for both clusters due to

```yaml
{{ $isClusterInitEnabled := and (eq (len .Values.conf.join) 0) (not (index .Values.conf `single-node`)) }}
{{ $isDatabaseProvisioningEnabled := .Values.init.provisioning.enabled }}
{{- if or $isClusterInitEnabled $isDatabaseProvisioningEnabled }}

````
So I end with an uninitialized database cluster.

What would be the best way to do this? Can we have something like

```yaml
init:
enabled: true
```

to explicitly enable the init on one of the clusters?
