Hum... I can't say I have the same problem. I do 95% of all global corrections in Lightroom (ACR would apply since they have the same rendering controls).
I see the need for rendering controls that produce a desired appearance that you can save and use often on other similar files. The same could be done with a profile but when the rubber meets the road, what's the difference? A LUT, a Profile or a set of metadata corrections.
The result is the same of course, but the workflow different.
It's the overlay effect: I'm twiddling one set of controls, but looking at the effect through the "filter" of my "signature look profile". I have several of these, I dial in a look, and twiddle. Say the look says less magenta (for faces) then even while I add saturation, the faces have less magenta ...
