The biggest problem with cup'n'cone is that wheels almost always turn up from the factory with way too much preload for some reason, and for the bike shop to rectify this, they have to spend time doing themselves out of further business which might amount to a whole wheelset.
I always adjusted the hubs on any bike I built, but it was against the boss's wishes. It wasn't a big effort, and it wasn't in any danger of coming undone in a hurry - usually it was just a matter of unwinding a pair of cone wrenches against each other and the locknuts, without loosening the locknuts if I could help it. Often one of the locknuts would move with the cone, and the adjustment would be locked in good and hard. This technique obviously not an option on stupid obsolete freewheel hubs...
