Disabling IDNA makes libcurl-minimal suited only for programs that only
communicate with a predefined set of servers in ASCII-only domains. Any
program that accepts user-provided URLs will need curl-full to be able
to handle arbitrary domain names, even if the program speaks only HTTPS,
HTTP and FTP.
Yes. But how many domains using idn are there? I worked on idn support
in systemd, but when preparing the description of this change I realized
that I have _never_ once used an idn domain outside of testing.
And note that this is not about user-facing programs like firefox.
I assume that there might be _some_ use of idn in firefox. But for
command-line tools like curl this seems even less likely.
