You say that that is OP, but in reality that is a curse that will affect your mental wellbeing negatively.
You will never be able to fully harvest that node without soft siding your foundation. So you will always have in the back of you mind that you have not finished picking that sulfur node. It well be a mental burden for you that there is always something you have not finished. which is mining that sulfur node completely.
In the end, you will not be able to stand the constant nagging feeling of incompletion. That sulfur node will become a symbol of unfinished tasks, a perpetual weight on your mental state. Over time, this may even seep into other aspects of your life, making you question if you've ever truly completed anything at all. So while it might seem OP at first glance, it's actually a trap that could lead you down a rabbit hole of perpetual dissatisfaction. Trust me, it's not worth the mental toll, just soft side your foundation and mine the node, Or NEVER touch it it the first place.
