I think this needs to be seen in context. Consumer gear is designed with compromises compared to pro use, for "economic rationalization". Prices need to be reduced to make sales. It makes sense for pro gear to have reliable screw-on cables, as the equipment is more likely to be moved and cabling changed, and there are economic consequences for a cable to accidentally fall out in a complex patching network.
Consumer equipment (for most users) is more likely to be a set and forget installation, and if a cable falls out of a typical stereo system it would be reasonably easy to trouble-shoot and fix in comparison to a pro installation. If the pro- and consumer-version scenario of the BNC had eventuated, I would imagine that as the hifi industry developed in the 1960's that audiophile-quality equipment would have been fitted with the pro-version of the BNC's and basic audio equipment would have the consumer design.
