But you have to think about what prefixes a customer has. If BGP you need to generate prefix-list, if static you need to generate a static route. As you already have to know and manage this information, what is the incremental cost to also emit an ACL?
the unfortunate reality is that many networks are run by CLI jockeys, so the incremental cost of this can be high. There are no good general-purpose networking sources of truth, which means that usually provisioning databases need to be highly customised, which is only worth it if the scale merits it.
