`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@host:" as the changed
default syntaxw (user and host are optional), or "/user@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.
