Inconsistent recommendation for Offscreen Rendering Only (Vulkan)

The option Offscreen Rendering Only (Vulkan) has been in the OpenXR settings for a while. It is enabled by default for Android/Quest platforms.
When I hover over it it says ‘This setting should be disabled for handheld platforms’

To me this sounds like it should be disabled for the quest, or am I misinterpreting what this means?

When looking through the Meta recommendations, they say it is a free memory improvement:

So what should we do with this setting, and can we change either the description or default setting based on what Unity recommends?
