Would be cool if, in newer updates, it became possible to manually drill down into the rockbore (or that it became strictly necessary to do so, due to the bloom infestation crusting over the seabed). To see the full extent of the bloom infestation, see proof that the infestation is taking over the planet from the bottom out.
This also would then include an upgrade to the depth mod for the tadpole, perhaps down to 650m, as well as different kinds of hulls?
