Installer depend on unfree software and therefor at least must go into contrib. There was some discussion, whether they should altogether go to non-free. See debian-devel for that.
That't true for packages that only consist of an installer. However, I don't see a reason in Policy which forbids the inclusion of an installer into a packages in main if this packages also includes other programs. For example, alien also includes (now outdated) special treatment for Sun's JDK RPM packages.
