Why the id field is missing from the Payload collection Select interface types?

[MurzNN]

Let's get a simple "Users" collection from the "auth" example: it contains generated types for the "Users" collection here:
https://github.com/payloadcms/payload/blob/b6b6bab4659516f66a537700ed54e3d27a46d3e2/examples/auth/src/payload-types.ts#L134:L147

export interface UsersSelect<T extends boolean = true> {
  firstName?: T;
  lastName?: T;
  roles?: T;
  updatedAt?: T;
  createdAt?: T;
  email?: T;
  resetPasswordToken?: T;
  resetPasswordExpiration?: T;
  salt?: T;
  hash?: T;
  loginAttempts?: T;
  lockUntil?: T;
}

There are all defined fields listed, but the id field, which should be present in all documents, is not listed. Therefore, Typescript shows an error that the id field is not allowed in this type.

Is this intentional and we should add the id field to this type manually for such cases, or a bug?

Yes this is intentional because theid field is always selected.

Thanks, understood! But the interesting thing, if a collection uses a custom id field settings, something like this:

export const Countries: CollectionConfig = {
  slug: 'countries',
  admin: {
    useAsTitle: 'name',
  },
  fields: [
    {
      // ISO 3166-1 alpha-2 country code.
      name: 'id',
      type: 'text',
      required: true,
      unique: true,
    },
    {
      name: 'name',
      type: 'text',
      localized: true,
      required: true,
      unique: true,
    },

Then the id field appears it the schema ;)
