I don't have real context here, but I can imagine that a platform where the hardware costs millions of dollars, will be booted up in "Production" exactly once, and is guaranteed to be physically destroyed before it hits 1 day of uptime, just "Give it 128GB of RAM and YOLO (literally)" is great advice!

Note: 128GB of DRAM may add another million dollars to the build cost by 2027 at the current derivative of the $/GB curve
