Plugin is removed from operator-sdk

[legal90]

Hi dear maintainers, and thank you for your work on this plugin!

I tried to use this plugin with operator-sdk v1.38.0 and it doesn't work:

$ operator-sdk init --plugins=hybrid.helm.sdk.operatorframework.io  --domain=example.com
Error: no plugin could be resolved with key "hybrid.helm.sdk.operatorframework.io"
Usage:
  operator-sdk [flags]

Examples:
The first step is to initialize your project:
    operator-sdk init [--plugins=<PLUGIN KEYS> [--project-version=<PROJECT VERSION>]]

<PLUGIN KEYS> is a comma-separated list of plugin keys from the following table
and <PROJECT VERSION> a supported project version for these plugins.

                             Plugin keys | Supported project versions
-----------------------------------------+----------------------------
     ansible.sdk.operatorframework.io/v1 |                          3
 deploy-image.go.kubebuilder.io/v1-alpha |                          3
                    go.kubebuilder.io/v4 |                          3
         grafana.kubebuilder.io/v1-alpha |                          3
        helm.sdk.operatorframework.io/v1 |                          3

For more specific help for the init command of a certain plugins and project version
configuration please run:
    operator-sdk init --help --plugins=<PLUGIN KEYS> [--project-version=<PROJECT VERSION>]

Default plugin keys: "go.kubebuilder.io/v4"
Default project version: "3"


Flags:
  -h, --help                     help for operator-sdk
      --plugins strings          plugin keys to be used for this subcommand execution
      --project-version string   project version (default "3")

FATA[0000] no plugin could be resolved with key "hybrid.helm.sdk.operatorframework.io"

And then I found that this plugin was removed from the operator-sdk upstream:
operator-framework/operator-sdk#6833

Reason:

Remove hybrid-helm v1-alpha support, due to low adoption, in favor of maintenance simplicity.

Questions

1. Will that that plugin be eventually deprecated? Does it worth for the community members to try using it for new projects?
2. If it's still alive and will be maintained - is it possible to use this plugin with latest operatior-sdk, when it's not bundled anymore? Is there a way to install it as an external plugin?

Thank you!
