On long sections of I 82 in Washington and I 5 in California, they famously have them for many kilometers going over the Cabbage Patch and going over the Grapevine. Mostly because any RVs or big rigs climbing are going to be weight-to-effective-power competitive with a bicycle going up them, the speed difference can be quite dramatic. I'm still in favor of going with treating them as any other lane, maybe tagging for the restrictions in place (like I 82 being hgv=no|yes|designated where the rightmost lane is a marked slow vehicle lane). I'm not sure there's really a way to accurately tag for the single-white "cross with extreme caution" line as opposed to the double white "no lane change" or white and broken white "lane change only in one direction" lines...
