Lightroom: Add user-selectable "performance vs precision" switch for Developer module so I can edit smaller versions of the RAW

I filter my 24MP Nikon D750 photos on a 4k monitor with LR CC on my mac (4.7GHz quad 4790K) in LIBRARY using 1:1 pre-rendered previews which is OK speed.

When it's time to develop the images in DEVELOP, the previews are ignored and LR loads the raw file and renders the photo because (as a LR dev has said) that's the most precise way to do it. I think this is great for landscape photographers that pour minutes/hours into a single photo but as a portrait/wedding photographer, I have to hash through a thousand shots per job. I want speed at the sake of precision.

I want the option to force LR to render a lower-resolution proxy version on my 4k monitor so that the sliders are responsive and the shot-to-shot times are as quick as possible. At 4k screen resolution and aforementioned faster-than-fastest CPU available today, those shot-to-shot loads are 2-3 seconds before I can start moving the sliders (worse if 280X GPU is enabled!)

BUT BUT BUT, when I go into the system preferences of my mac and tell the OS to scale my screen to emulate a 1080P monitor, LR becomes incredibly responsive because it's now rendering for a smaller res. At this point in the workflow, sharpness/focus has been determined and I only care about colors.

Please give me a small proxy edit version!
