Why are US beekeepers so derogatory about supecedure? Why is it a "problem"?

If you are trying to maintain a certain line of bees in your hive - hygienic
for example - the first time they supercede the trait is basically lost.
(You can't raise collies if you let the mom out the back door at night.)
Further, if you spend a lot of money on queens you want to get more than a
couple months out of them.

If you are trying to develop a healthy acclimated stock, without selecting
lines, natural supercedure would be a good thing. In the pre-mite days I
regarded a supercedure queen as an excellent queen if she was laying
properly and the bees weren't mean. Now we are trying to raise
mite-resistant bees using breeder queens and subsequent selection.
