Hi,
in my view it should not run by default.

Installing the service by people who know what it is could not be a problem, and by people who don't know what it is maybe it is a good idea for them to learn something about it before installing.

Let the user decide by himself what kind of SSH and how will he use, if he decides to use the service at all.

P.S. Is there anywhere on the Net a SWOT analysis of the SSH service.
