Sure. I don't time it, but yes, it can go fast. Very special pictures will see more care, but speaking of like a Baltic vacation with 1200 pictures, plus 500 on the wifes compact, yes, one evening. You still might come back and work on a few special ones more, for other purposes.
Buying a USB 3.0 card reader speeds that up. When outputting all the JPG file batch, you can go get coffee or glance at the TV news.
But opening one and tweaking exposure, what? Five seconds? You see what it looks like.
White balance can be five seconds or could be much longer.

Again, you see what it looks like (but yes, there are some tough ones).
Cropping, say five seconds? Again, you see what it looks like.
All of these steps might involve a second try, to see possibilities, but there is not much to it.
In many cases, you might do many similar pictures in one click (at least with Adobe Raw).
My concern is those that simply will not consider doing this necessary step.
