Thank you for your detailed explanation. Regarding your comment in the second e-mail you sent, I am using 2.14.1 so I am on the latest stable version. We are looking at some examples of KML generated by other software and they do have zoom dependent rendering which makes me think that it is not a KML limitation but an SLD to KML translation in GeoServer issue.
Providing funding for the development of this functionality from GeoServer is an option and I would be able to provide examples in that situation. The company I represent has asked for a quote on the development.
