NPM only gained minimum package age in February of this year, and still doesn't support package exclusions for internal packages. https://github.com/npm/cli/pull/8965 https://github.com/npm/cli/pull/8965 https://github.com/npm/cli/issues/8994 https://github.com/npm/cli/issues/8994 Its good that that they finally got there but....
