How important are the caveats relative to new camera specs?

I'm the guy with lots of questions and a few observations but very little expertise! Better to be thought a fool than to open one's mouth and remove all doubt, is always in the back of my mind.
I've followed the 6D2 banter until recently "unselecting" the threads, and all the emphasis on DR kind of put me into the following mindset.
A blog by a well known bird photographer first got me really wondering about the quoting of specs of cameras and what the specs actually mean relative to real life. Here is the quote that was made relative to the shutter speeds of the 5D4 and 1DX2 (I am not interested in promoting negativity towards the individual so please don't go there):
"While both of the pro bodies, the EOS-1DX (12 fps)and the EOS-1DX II (14 fps), are a lot faster than the 5D IV (7 fps), do understand the following simplification: if you are working at 1/1000 sec with a camera that has a frame rate of up to 14 fps, you are missing 98.6% of the action poses in a given second. If you are working with a camera that has a frame rate of up to 7 fps, you are missing 99.3% of the action in a given second. This is not a great difference … (Note: the up to stems from the fact that the frame rates quoted in the specs are for One-shot or Manual focus. The frame rate drops considerably when you are working with AI Servo AF. And that drop itself varies and is related to some of your AF Menu choices."
My interest is in understanding exactly what is a fair assessment of the advantage of more fps relative to real life shooting situations. However, I'd like to take it beyond just that to the camera specs in general. Like number of AF points, as another example. Such specs are often used as clubs in CR debates (arguments).
It seems to me that most specs have caveats and often these are very important but likewise often overlooked.
So I started looking for reviews that do measurements relative to spec comparisons and came upon this site:
http://www.imaging-resource.com/PRODS/sony-a9/sony-a9A6.HTM
I was comparing what is given as shutter lag between the Sony A9 and Canon cameras (the 6D2 is not there yet) and wondering how that particular characteristic shows up in real life shooting, and is it important. So far I don't think I've heard it ever mentioned when a camera is being derided.
This should be enough to provide a feel for what it is that I'd like to provoke some discussion on and thereby learn how to be more discretionary in viewing manufacturer's specs. I've mentioned a few specific examples but am more interested a broader discussion. What specs are most important and how important are the caveats associated with them?
Another example just popped into my head: the 6D2 focuses at F8 but the caveats are very significant!
Hope I won't be the only one having an interest in this thread.
