So if it's a domain, you should fully qualify it: https://foo.zip.
Over time, this can become a convention. Part of the price you pay in using a .zip domain will be that software doesn't auto-linkify it unless you prefix it with http(s)://.

I don't see a reason for adding these new TLDs other than a cash grab.
Furthermore, why not use port numbers as a suffix? That's how we can have umpteen services across different protocols on a single domain.
