In reply to John Ww:
Not really or at least exclusively elitist, but more to do with tradition (plus environmental zoning rules) preventing retro bolting. Most routes at those grades simply were established before the sports bolting era, so just bring some trad gear and slings for the IIIs and IVs.
FWIW I would support blanket rebolting of most beginners' routes, but could of course not be bothered to do it myself. Unfortunately these grades are also way below the level of the new routers. Still, some new crags have routes at that level and are well protected, but that is some commendable community service!
And anyway, if want to experience truly shit pro and insanely placed first bolts, give Saxony try, especially on the easy stuff. After almost 15 years of living in Dresden, Frankenjura feels like Finale!
