VPLEX Witness and spectre/meltdown vulnerbilities

Hi, I note as part of article 516617 (link below) and the recent spectre/meltdown vulnerabilities, the article states the VPLEX Witness is affected and to check with the hardware system vendor or hypervisor vendor for any available updates for the host system to prevent attacks. Our customer has confirmed that they don't patch any external builds and expect us as the vApp vendor to provide a fixed version. The last comment in the article details states that a remediation plan for the guest OS is in progress (due end of March 2018), can somebody in the product development space tell me if this will specifically include the vApp VM patch? Just so that it's clear and I can communicate expectations to my customer as there is a fair amount of visibility around this.
