kyaml: yaml anchors get replaced

[FernandoMiguel]

yaml x-anchors are being deleted and inline values replaced.
the whole point of having the anchors is to make it easy to know what values require changing.

x-anchors:
  environment: &environment "alpha"
  internalDnsName: &internalDnsName "test-app.example.com"
  serviceAccountName: &serviceAccountName svcacct
argo:
  clustersgroup:
    - alpha

deployment:
  environment: *environment
  serviceName: test-application
  serviceAccount:
    create: false
    name: *serviceAccountName

#kyaml 
---
{
  x-anchors: {
    environment: "alpha",
    internalDnsName: "test-app.example.com",
    serviceAccountName: "svcacct",
  },
  argo: {
    clustersgroup: [
      "alpha",
    ],
  },
  deployment: {
    environment: "alpha",
    serviceName: "test-application",
    serviceAccount: {
      create: false,
      name: "svcacct",
    },
[...]
  }
}

Since the anchors remain when I run it through the basic formatter, it probably means when the kyaml formatter produces its output it does not consider anchors from the AST representation. That would be a feature request to that package to allow yamlfmt to support it.
