More precisely, the proposal (as I understand it) is to block downloads 
carried out via HTTP links from sites that themselves load via an HTTPS URL.

So provided the downloads are also served via HTTPS (as they should be, 
to minimize the risk of tampering), they're not affected by this.

Perhaps it's time to enable HTTPS on those TL/CTAN mirrors....
