Status of native Haswell raminit

[Matt B]

Greetings,

What is the status of native raminit on haswell? It's the first generation
that doesn't have a native implementation.

I did find some seemingly successful past work [1] but what happened to it?
Did it run into a blocker issue or was it just abandoned in favor of other
priorities?
