      So suppose a user often uses Tramp to connect
    to other machines, where ssh is used.  Now the user connects to a new
    machine which does not provide ssh but telnet.

There could be various options to control autodetection; one could say
whether to try telnet or not, and another could say whether to try ftp
or not.  People who want security could turn off autodetection's use
of telnet and ftp.  Then they would have to specify those methods
explicitly when they want to use them.

Perhaps the defaults should not include telnet or ftp, and you should
have to request them explicitly when you want them.
