Re: TRAMP password caching

[Richard Stallman]

    Sounds good, but if the user has to change its config to get Tramp/scp to
    work acceptably, then she may as well change tramp-default-method.

That is true, but using ssh-agent is convenient in general; lots of
people will be glad to switch to it once they know about it.
(I was.)

    So I think the default should be "ssh" because it's the only setting that
    works acceptably without any need for the user to use
    a particular ssh configuration.  Then we can tell them "if performance
    sucks, use scp which involves these and that changes to your SSH config".

Maybe.  I would like to see if anyone else objects.
