The situation is still very unsatisfactory. "Fagradalsfjall" is still not visible in OSM (only as "alt_name" of its highest peak "Langholl", if you deliberately search for it on OSM, and hardly anybody is going to do that...). Also "Fagridalur" is not visible in OSM, since - tagged as "natural=valley" - it is not rendered. Now somebody has chosen to call the new lava field "Fagradalshraun", although Fagridalur is really opposite the fjall, which is utterly misleading. Maps are forming media coverage, and unsatisfactory maps cause wrong media articles. And this only happens for the sake of keeping the systematics of OSM right, ignoring whether it is useful to the public... This is very disappointing...
