Why is list of available fonts so limited?

[BARNZ]

I would like to use the Calibri font but doing the following causes excel to complain about worksheet errors:

$sheet->writeHeader($headings, [
    Style::FONT => [
        Style::FONT_NAME => 'Calibri',
        Style::FONT_SIZE => 10,
        Style::FONT_STYLE => Style::FONT_STYLE_BOLD,
    ]
]);

I see theres a function Style::_getFamilyFont() which has $defaultFontsNames. If I add Calibri to this array then things work, but I cant see any way to add to this array from my application code:

$defaultFontsNames = [
    'Times New Roman' => [
        'name' => 'Times New Roman',
        'family' => 1,
    ],
    'Arial' => [
        'name' => 'Arial',
        'family' => 2,
    ],
    'Courier New' => [
        'name' => 'Courier New',
        'family' => 3,
    ],
    'Comic Sans MS' => [
        'name' => 'Comic Sans MS',
        'family' => 4,
    ],

    +++++
    'Calibri' => [
        'name' => 'Calibri',
        'family' => 5,
    ],
];

2 questions:

• Whats the reason for this list of 4 specific fonts only? And of all fonts why comic sans as one of these 4? 😆
• Can we have a way to set the default available fonts - or rather can we just use any font we like in the style array?

FYI just found this library and am currently trying to port some exports over from the now archived box\spout library,
