Getting your CA into a trust store means that every machine using that trust store will accept your certs. It’s not really necessary for a government or corporation to have a public CA in anyone’s trust store unless they want to issue certificates that everyone trusts. If they just need their own machines to trust their certificates, they can use the management utilities that come with Windows and with AD to distribute an “enterprise root”, which only their machines will trust. This is how most large companies and governments do it.
