These do not have to be tiny as they are available as SVGs.

Just because a logo is a vector art doesn't mean you can just naively scale it up.

I'm aware, that's why I checked a few to make sure these actually scale well.

Normally when you make a logo bigger, you'll increase the level of detail, and tweak line widths.

I don't know if this icon set provides this, but there's no reason SVG can't provide different levels of detail for different scaling factors.

Yes. Line art can be tough to scale properly.
