I think bits of SRAM per unit of area is a benchmark that some people use, as it corresponds to something that's meaningful and measurable.

The problem is even that is flawed as things are going three dimensional.

So just start measuring in bits of SRAM per unit of volume?

That's a problematic metric as well because we don't know how much area the assist circuit takes up. Modern high-density SRAM cells cannot operate as is, they need an assist circuit to compensate for variations. For example for Intel's 10nm SRAM, they claim 77% area effiency (https://fuse.wikichip.org/news/525/iedm-2017-isscc-2018-inte...). But without those values, just bits/mm2 or so is problematic.
