Seems if I add the package names to ignore entry in the config then the changelogs aren't generated. Though I'd expect private to behave similarly since docs say to avoid ignore and use private: true instead.

I ran into a similar issue: even though an internal package in a mono repo is set private: true, I can select it when running changeset. If I add it to the ignore array, all works as expected, but according to the documentation this should not be used permanently.

btw, if you try to use ignore to workaround this, it doesn't work.
I run into this:

🦋  error ValidationError: Some errors occurred when validating the changesets config:
🦋  error The package "clibuilder" depends on the ignored package "cjs-plugin", but "clibuilder" is not being ignored. Please add "clibuilder" to the `ignore` option.

Because I'm adding the test package (cjs-plugin in this case) as devDependencies.

Any news here? This issue can lead to congested changelogs when you have many private workspaces.

If you set this in your config:

  "privatePackages": {
    "tag": false,
    "version": false
  }

Tags, version bumps, and changelogs will all not be produced.
