Maybe they SHOULD go ahead and make 4 versions of each facet map (facetw00.dds, facetsp00.dds, facetsu00.dds, faceta00.dds (examples based on KR file setup)), have one big patch to get them down (or patch them in over the course of a year as the seasons change) and have a routine that changes the facet map called based on the calendar timeframe for the local server.
But that's just me.
