[Request] Filter packages shown in CLI when writing a changeset

[quantizor]

Affected Packages

@changesets/cli

Problem

I have three packages in a monorepo, and only one of them is actually publishable (the others have private: true.) When I run yarn changeset, it asks me which ones I want to write changesets for, including private packages. I very rarely change these other packages and dislike that the CLI forces me to choose which package to bump every time when the others are never relevant.

Proposed solution

1. Allow config to focus the CLI, specifically changeset add to a specific package or list of packages, or
2. Add a flag to changeset add to omit unpublishable packages

Digging into the code, I noticed that there is an explicit check to ensure that version is not set for packages marked as private: true, why is that? Would it be OK if I removed that limitation?

Are you referring to this check?:

changesets/packages/cli/src/commands/add/isListablePackage.ts

Line 11 in 0bf89b3

if (!config.privatePackages.version && packageJson.private) {

That's actually reading out of the config. So if you set "privatePackages": false in your config.json, it will ignore private packages (whether they have a version or not).
