OK, sorry if I over-reacted, it's just that I've only recently realised that much that I thought was pretty much universally accepted apparently isn't when it comes to retrobolting!

I'm still no sure that perceived under-usage is a justification for putting a lower-off on a trad route, particularly where its predominant characteristic is boldness and adventure. I'm not sure the lack of a convenient belay at the top is main reason that Bones Chimney gets done so rarely.
I don't know about the more recent E5 and E6s, I guess you'd have to ask the first ascensionists but it seems to me that you are going to commit to a big scary trad route, it really isn't too much trouble to stroll round to check the top-out. Put a stake in if necessary and dangle a bit of rope. You'll have to belay from the top in most cases anyway won't you? Or are you concerned that checking the top and fixing a belay blows the on-sight?
Why does it bother you so much if some scary routes don't get done very often? Are you on commission or something? This is a general point that is coming up quite often, it's not just aimed at you.
