ssh client read only mode

Hi all,

I am looking for ways to have the openssh client [1] run in a read only
environment nicely. Will there be an option or flag to avoid
creation/edition any of files of the base system?

The reason I am asking is that command strings like [2] will for example
not stop the ~/.ssh creation attempt [3] as looked at the code in for
example the current trunk or else, which forces me to use a lower
LogLevel to avoid the output of this message, which just does not seems
pretty to me ;-)
