Then "M-x calendar" should take care of setting the default-directory
of its buffer.  It cannot be done by the infrastructure, because in
many cases when a buffer is created, Emacs doesn't yet know its future
purpose.

But we are arguing about issues that might be purely academic.
Michael asked you to collect some Tramp-related data, so he could look
into what happens in this particular case.  Please provide him the
data he asked for: it could very well lead to a simple and
uncontroversial solution.

The default-directory of *scratch* is the directory where you start
Emacs, so it's not a fixed directory, and I don't see how it can serve
the model for anything referenced in this discussion.
