Personally I would say a big no to building it out in the "training required" direction.
There is more than enough for the dedicated crafter types to do already, with more still to come in the form of stone masonry etc when EK buildings are worth putting in the effort to build. Ya'll just had to cut swaths out of the early crafting loop to get new players to "minimally viable", so I would hate to see things added that make it harder to achieve that in the form of essentially required food buffs. If they are not interesting, important or essential enough to be expected or required, then they are not going to interesting or important enough to put valuable passive training time into except as a dump value a few years into training.
I also think food and the skill-less to gather collectibles are a great way to introduce players to the crafting system, without gating yet another thing behind passive training.
But that's just my opinion
