For example, above link shows:

 "grc-grek": {
            "examples": [],
            "font": {
                "family": "Ezra SIL",
                "source": [
                    "SILEOT.ttf"
                ]
            },
            "oskFont": {
                "family": "KbdHebr",
                "source": [
                    "KbdHebr-Regular.ttf"
                ]
            },
            "languageName": "Greek, Ancient",
            "scriptName": "Greek",
            "displayName": "Greek, Ancient (Greek)"
        },

From .kps:

  <Keyboards>
    <Keyboard>
      <Name>Galaxie Hebrew (Mnemonic)</Name>
      <ID>galaxie_hebrew_mnemonic</ID>
      <Version>3.3.1</Version>
      <OSKFont>..\..\..\shared\fonts\kbd\kbdhebr\KbdHebr-Regular.ttf</OSKFont>
      <DisplayFont>..\..\..\shared\fonts\sil\ezra\SILEOT.ttf</DisplayFont>
      <Languages>
        <Language ID="hbo">Ancient Hebrew</Language>
        <Language ID="he">Hebrew (Hebrew)</Language>
      </Languages>
    </Keyboard>
    <Keyboard>
      <Name>Galaxie Greek (Mnemonic)</Name>
      <ID>galaxie_greek_mnemonic</ID>
      <Version>3.3</Version>
      <Languages>
        <Language ID="grc-Grek">Ancient Greek (to 1453) (Greek)</Language>
        <Language ID="el">Modern Greek (1453-) (Greek)</Language>
      </Languages>
    </Keyboard>
  </Keyboards>

We can see that the font data is not present for galaxie greek so should not be shown in .keyboard_info.
