Variable fonts?

[strarsis]

So glyphhanger can convert variable fonts (as some newer ones from Google Fonts) as traditional/static fonts?
The generated CSS by glyphhanger does not have a font-weight range for that font family. Is that font-weight range required?

Follow up: Font tools (with WOFF2 support) report font axes, like this tool.
Blog post that use glyphhanger or the underlying pyftsubset tool write that those tool also work with variable fonts.
