It was a change from Cygwin 1.5, yes.

It's fine if you were comfortable with more of your environment seeping
through the 'ssh' connection.  But your comfort is not really the issue.
Exposing specifics about your environment opens any connection up to
exploitation.  This is true for 'ssh' in any environment.  Check the
email archives for a discussion of this change if you're interested in
more details.
