Now after feature freeze of the new version I wanted to address this topic to the Release Management Team.

Opinions?

The one response you got on pgsql-general suggests that this isn't a
proposed change to PostgreSQL but rather a proposed change to
EnterpriseDB's packaging of PostgreSQL.  The RMT has no jurisdiction
over EnterpriseDB's packaging of PostgreSQL, and I have no personal
knowledge of that topic.  You could contact Dave Page about that
issue, perhaps.

If there is a change to PostgreSQL itself proposed, the RMT could
consider granting an extension to feature freeze for that change if
the larger PostgreSQL development community felt that the change was
worthwhile, urgent, and low-risk.  However, the RMT would probably not
want to make such a decision about the matter without hearing from
those community members who know something about Windows, or in
advance of the patch having been written.
