Has anyone tapped out 128gb of RAM? If that's the case, can you share examples and stories?

Sounds great.
You'll probably want to hear of use cases to justify the dev time... For me, it was something I'd loved to have on every job when rendering against a real world photo plate. Especially in product renders, or mockups where you get a background with visible DOF. Using postproduction to compose the render over the original backplate is viable only if the rendered content is sharp everywhere. As soon as it gets blurred from DOF you'll have the problem that your rendered image will still have some info of the double-DOF in non-black alpha areas which can be problematic in post, up to the point where you can't get a good result depending on how extreme the Bokeh is.
If you know in advance that you will comp the image, then the image should always be rendered over black (environment primary rays not visible to camera). Then there is always no problems with anti-aliased pixels, no matter how much DoF or motion blur there is.
Personally I never understand why anyone renders over anything else but black, as the minutes it takes to put image A over image B in comp far outweighs the hours of re-rendering because you forgot something, or you needed to colour correct something a little.
I'd rather see that dev time go to towards actual limiting bugs in Corona.
