(I don't count formally.) I think I agree with Even's position here. And, I see this as not being "GDAL's own way", but "a proposed way for the open geospatial community". But, overall this makes me wonder: Are there any formats for expressing epoch in the open source/open format world, and also in the proprietary world?. I'm not aware of any (which means epsilon more than zero) and a quick search did not turn up anything. Obviously the US NGS keeps track of such things in their bluebook and NGS Integrated Datbase formats as they transform positions among epochs when doing adjustments, but that's a rather specialized and not so relevant to GIS format.
