I don't think it depends on the writer. Remember, "The Sweet Spot" and "Brawl in the Family" were written by the same person. In TSS the parents were competent, while in BitF, they were useless... and they were written by the same person. So I don't think it depends on the writer.

Maybe you should look at NSL as an Alternate Universe, and not canon, same with BitF. That's how I see these episodes, an Alternate Universe.
