Description

Is your feature request related to a problem? Please describe. Currently all links are prefetched including ones intended for downloadable assets. Since these links could point to large payloads (imagine multi megabyte PDFs or zip archives) that's quite a waste of bandwidth.

I'd argue excluding links which have the download attribute would be a sensible default.

Describe the solution you'd like

document.querySelectorAll('a:not([download])')

Thank you :)
