`simplified' is not an old-style compatibility. The "old-style" syntax,
allowing the method name to be optional, has been thrown away
completely. You use now either "/method:user <at> host:" as the changed
default syntaxw (user and host are optional), or "/user <at> host:" as the
symplified syntax (user being optional). Simplified syntax looks similar
to the old ange-ftp syntax.

With the simplified syntax, you declare your default method via
`tramp-default-method-alist' or `tramp-default-method'.

I'm marking this ticket as notabug and closed, but of course we could
continue to discuss how to optimize your settings.

Best regards, Michael.

Hi. I'm running a bleeding-edge build of emacs from git. I turned on
what I thought was the old-style TRAMP syntax by evaluating

  (tramp-change-syntax 'simplified)

This gives me the old syntax for ssh, but other modes don't work
anymore. For instance, trying to open /sudo::/whatever now tries to
contact an ssh server named "sudo". Is this expected? Is the 'simplified
syntax not an old-style compability syntax?
