Aside from the obvious, the thing I can't stop thinking about is how the Deepground stuff fits into the narrative. At a point in the original, the threat from Sephiroth/Jenova is so great that Shinra basically reallocates all resources to stopping him. If the threat is great enough to relocate the cannon to Midgar and train it on him etc, surely it is also great enough to unleash all the crazy shit in the basement. In the original canon you can explain this away, just barely, that nobody with the power to make that decision really knew. It was fringe experimentation in a sealed unit. But with the Remake canon now demonstrating it's just an elevator button away and Scarlet is able to summon Nero with the press of a button, it feels like when Meteor is in the sky and everything goes to shit Deepground has to have a role.
