Not sure your reasoning for the questions. :?
But to answer your questions, No, partly, and No.
My comment was to point out that using bee boards, and yes, I have seen hobbyists use them, is not feasible with top only entrances. On this forum, all types of ideas are discussed. Why divide something into groupings of what migratory or big operations do, when ideas may or may not be suitable for any or all beekeepers, or applies to none.
I don't usually use much more than smoke. But I also use the knowledge that when supers are filled and completely capped, and you do smoke bees, they run to open cells to gorge themselves. This is what bees do when you smoke them. So by smoking the bees, they will run out of the supers as they are seeking open cells.
Of course this will not work for those supers with brood, or areas with open cells. But if you manage you bees properly, and even have the knowledge to get effective use from queen excluders, it really takes little effort to take completely filled and capped supers off the hives with little attached bees.
Many beekeepers smoke their bees, encourage them to seek open cells to gorge from, and then wonder why they have problems clearing bees out of supers, even with fume boards, all the while having open cells in the supers. Bees will cling to supers and ignore smoke and even fume boards after a beekeeper just signaled a coming fire. Smoke gets one reaction, and it sometimes is a bit harder to over rule this instinct, 30 seconds later, by getting them to react to another instinct by asking them to clear supers.
