I think, in full generality, “Nutrition is complicated and multidimensional, and the more you restrict along any axis for any reason the more tradeoffs you need to make and considerations you need to take to ensure you’re getting what you need.”
I’m also not sure if relying on traditional vegan dishes and cuisines is sufficient, if your metabolic context is very different otherwise? E.g. I suspect a farm worker who needs to eat 4000 kcal/day to do all his physical labor has to worry a lot less about specific food choices to ensure he gets enough of key micronutrients, and just eating a reasonable amount of variety is usually going to be good enough. Getting everything you need from, say, 1500 kcal/day is a lot harder, and if you cut out a whole subset of the most nutrient dense foods on top of that you will likely miss something. Maybe majorly, and it shows up in bloodwork at your next physical. Maybe only slightly, in a way that takes months to years to notice and then is similarly hard to pinpoint and that no one else around you thinks is a thing.
