remote-global-parameter4-set command allows to configure kea with non existing parameters

command:

{
  "arguments": {
    "parameters": [
      {
        "name": "boot-fiabcsd",
        "value": "/dev/null"
      }
    ],
    "remote": {
      "type": "mysql"
    },
    "server-tags": [
      "abc"
    ]
  },
  "command": "remote-global-parameter4-set"
}

so I used non existing name. Result:

{
  "result": 0,
  "text": "DHCPv4 global parameter successfully set."
}

It wouldn't be bad but after kea reconfigure it accepts this as correct config and config-get returns:

{
  "arguments": {
    "Dhcp4": {
      "boot-fiabcsd": "/dev/null",
      "config-control": {
        "config-databases": [
          {
       [...]
