Good point, but I'll press my case a little further.
Wind direction is easy to forecast several days in advance, both through government weather resources and sites like Wunderground and Weather.com. So we all have a pretty good idea what the likely runway will be.
A few months ago I was planning a trip to Cincinatti or Mansfield Ohio and realized that the most likely (given the winds and therefore runway) STAR would probably cause me to file for a slightly different routing than if I was going direct. Looking at the STAR allowed me to check for terrain, TFRs, etc.
If you fly into some of the Northeast of NYC airports (e.g. HPN, DXR) on a bad weather day you're pretty well guaranteed to get the Nobbi5 arrival. First time that happened to me I was on my way to a fix much further south and if had known then what i know now I'd have filed for a more Northerly route ending in the starting fix for Nobbi.
So I agree there is no need to make this a top priority, but a nice to have for sure. It won't often have a major impact on time and fuel consumption calculations but every little bit of accuracy helps, right? :)
Add the MOS data on ceilings and Cloud Tops? And,
MOS forecasts to each airport along the route that doesn't have a TAF?
