I think it's feature that suits certain boats and not others. For example I've seen a C&C 44 fitted with a similar (though taller) fixed windscreen and it really didn't look "right".
From a practical standpoint, few "soft" dodgers ever get folded down anymore... Most now have lexan windows that don't lend themselves to collapsing, so though made of canvas and plastic, they are no less "permanent" than the windscreens you speak of. Yet they are far more "accepted" as a cockpit protection than a fixed windscreen. I think to a certain degree, with notable exceptions a windscreen like that is considered a "powerboat" feature.
So I guess it boils down to popular aesthetics. The HRs and Najads look right because they've always come that way. btw the BC built Sceptre 41/43s, big, solid pilothouse boats have always been offered with fixed windscreens too...
