Lightroom: Desaturate Highlights and Shadows

I want to second this.  Another example is during weddings. The white dress often picks up blue from sky or yellow from warming filters.  It would be nice to be able to desaturate just the highlights without desaturating the overall color.

I want to be able to control the saturation of shadows, mids and highlights separately, or using a luminance/saturation curve. Davinci Resolve does it (http://nofilmschool.com/2015/11/simple-trick-make-your-color-grades-look-more-professional) as well as other high end colour grading tools.
This would be a really useful and efficient addition for me and I suspect a lot of LR users for correcting saturation imbalances in different luminance ranges as well as creating some beautiful looks, without having to use local adjustments or export to PS with all the added time and storage space that involves.

Obviously I can use a brush with a saturation adjustment, but to do that for many images is very inefficient if what I really want is just to adjust saturation in shadows say (without affecting contrast - could just use curves if I wanted to change contrast along with saturation), especially if I want to do the same thing for a set of images under similar lighting. 

The way I imagine it working is as a standard saturation control but effectively masked with a curve for a particular luminance range. Could be fixed curves for shadow, mid, highlight, or probably even better a user editable luminance/saturation curve.

This requires stepping out of the raw workflow and into Photoshop to create a luminance mask and adjusting from there. This very common process should be integrated into Lightroom.

100% yes! True, you can work around this using a local adjustment that essentially covers the whole frame but it is inefficient. If the capability is there for the local adjustment surely it can't be such a stretch to make this a global adjustment.
