Did anything ever come of this? Were the ideas ever implemented in the real world?
A great video about Fear of Depths briefly talks about this: https://youtu.be/7MOKTU9tCbw?t=1299 (timestamped at 21:39 when they mention WIPP, but I highly recommend the whole video)
Probably not, but it's interesting to think about.
Seems pretty trivial for this kind of lore to get started.
