I'd argue that they do have the logistics down pretty well at this point as HBM3E can squeeze 144Gb onto a package.
That makes it sound like they'll probably use software locks on one die to restrict RAM.
Downloadmoreram.com could become a reality!
Almost a zero percent chance that will happen as HBM is a stack of DRAM dies, capacity can be reduced by omitting additional dies. If the DRAM were directly integrated into the CPU's die then maybe we could see software locks however historically that would be accomplished by physically laser cutting the traces (unless you are AMD and forget to with the K10.5)
