`curl-minimal`+`libcurl-minimal` are compiled with various
semi-obsolete protocols and infrequently-used features disabled:
DICT, GOPHER, IMAP, LDAP, LDAPS, MQTT, NTLM, POP3, RTSP, SMB, SMTP,
SFTP, SCP, TELNET, TFTP, brotli compression, IDN2 names.
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.
