I'm pretty sure they intend to keep the distinction between grown ingredients and foraged ingredients. They motivate two separate kinds of activities.

I would like it if some tech upgrades would allow us to plant or relocate ingredients from earlier tiers. Those berry bushes have a lot of decorative potential. And it could be just one more small way to help players get back up to speed after a huge loss. I'm sure mods exist that already make that possible. Use at your own discretion.
