Issue: iced-rs#2455 Add a 'fontconfig' feature flag (enabled by default) that controls whether system fonts are loaded via fontconfig on Linux. Disabling this feature prevents loading all system fonts at startup, which can be very slow for systems with many fonts. Users can disable fontconfig in their Cargo.toml: iced = { version = "...", default-features = false, features = ["wgpu", "tiny-skia"] }
When the `fontconfig-explicit` feature is enabled, applications must
call `iced::font::configure()` before any text rendering:
iced::font::configure(iced::font::FontConfig {
load_system_fonts: false,
});
This gives applications explicit control over whether system fonts are
loaded, addressing the slow startup issue on systems with many fonts.
The feature is mutually exclusive with automatic fontconfig loading -
either use `fontconfig` (automatic) or `fontconfig-explicit` (manual).

Gl;hf. Here's somethings that perhaps possibly maybe are vaguely somewhat a little useful for #2455.
I actually recommend the core team not accept this contribution at all, and to dismiss it and do the work themselves. Again, gl;hf.
If anyone has any encouragement or guidance, I'd also be happy to try pursuing any of the many options available in rektide#1.
