A core feature of wikipedia is "no original research". It doesn't matter whether you think these occupations are obsolete or not. It only matters if someone else thought it, and wrote it down, and then got it published in a reliable source. At that point a wikipedia editor can add the occupation to the list.
It's a bizarre system because there are large cultural around fact-checking in different media in different countries, so there's a load of opinion that's now in Wikipedia because it got published somewhere else.
