"The 6D has more than enough DR." depends on what one wants to do. For most people, me included, 16 MP would also count as "more than enough MP" as well as cars don't need to run faster than 140 km/h. It's pretty much the same as saying b/w prints on RC have more than enough grayscale although one  can clearly identify the difference of RC paper prints and FB paper prints if both are exposed and developed carefully.

 

I still prefer having as much DR as possible although I know common displays or prints can't show 12 f-stops (of 6D). It's a bit of extra security if I can't check exposure after each shot on a live histogram. The one of the camera is just too tiny.

 

Anyway, if you say "silly shadow lifting" it doesn't sound you're fully-hearted using it?

A normal tonal curve shows about 7 to 8 stops. It is not about monitors and/or prints being able to show more (prints do about 6 stops). That leaves 4 to 5 stops extra headroom, that is why I say it has more than enough DR. 

You would not want to look at a 14 stops DR image, it looks very grey and very flat.

 

If you want to do HDR tonal mapped images, you are better of shooting more than 1 image. Also with a Sony sensor. Why? Because the information density (tonality) at the dark part of RAW is low. With 2 or more bracketed images, you resolve that issue.

 

I don't lift shadows, I do not dislike contrast. And if a scene is unattractive, I don't make photos of it. Or I discard the images. I don't try to make them a bit less unattractive by lifting shadows, as they remain unattractive...
