I'm figuring that this "fork on the tech tree" is going to be relevant to both terrestrial and space based nutrition production. The net result is that the production of proteins begins to decouple from "land area" needed to produce those proteins. Once "farmland" is no longer (as) necessary for the production process to make proteins for consumption, a lot of the production can be moved into laboratory settings in which greater (designer) control over the end products becomes possible. Once you have laboratories capable of producing meat proteins, that has implications for life support in hostile environments (such as space habitats, etc.).
I presume that technology along these lines is necessary in order to provide for the basic nutritional needs of populations on Non-agricultural worlds in Traveller, although (obviously) "vertical farming" and other "laboratory" environments for the growing of plants at an industrial scale to feed a population of millions to billions would obviously complement the type of carniculture technology being discussed in the above video.
In an interstellar culture, the ability to source FOOD and DRINK from somewhere other than the "natural" environment becomes absolutely critical to both interplanetary and interstellar expansion of that species. After all, if you can't eat/drink (or breathe) wherever you're going, you aren't going to be staying (alive) there all that long.
What this suggests to me is that Tony Seeba is RIGHT in his assumption that "older" artisanal means of agricultural production will continue, but will become niche premium products sought after by those who can afford them (and have the requisite tastes to support those producers). Viewed more broadly, this would in turn mean that worlds coded with the Agricultural trade code are worlds which have "enough" of these artisanal agricultural producers to supply an interstellar export market with their "unique" (to each world) agricultural products. It means that the artisanal farming methods are economically viable enough to compete in interstellar markets ... much like how wagyu beef now has an international cache to it which can command a premium price outside of Japan. Likewise, champagne can only be grown and bottled in a specific region of France, but has an international standing sufficient to support the export of that specific product around the world.
It doesn't mean that "everyone on an agricultural world is a farmer" (per se) ... but it does mean that (artisanal) terrestrial agriculture production is a large enough segment of the local world economy to be able to export agricultural production to interstellar markets, even if there are "cheaper local alternatives" in those interstellar markets (see: wagyu beef and champagne for market corollaries).
