I just installed Helm v3.4.2 and the command below prints many packages as DEPRECATED in the description:

`helm search repo stable`

Output:

```
stable/acs-engine-autoscaler            2.2.2           2.1.1                   DEPRECATED Scales worker nodes within agent pools

```

Why only 18 on 284 packages are not deprecated ?

Do that mean for these packages we have to add external repositories ?
