Yeah and I wrote the above. Yet maybe someone else knows the answer that you
don't want to look for at the source.

Good thing.

Well noise alone is one reason. Since you know HDR and you know you can
reduce shadow noise, then you can use for that if you need too.
IF you make a so called linear capture of a scene then you will not have
your so called scene look like the so called scene you are trying to
reproduce.
What you are not understanding is the development from raw is to make a
image look like your eye sees the images, not trying to reproduce the scene
values. Just as with film you are compressing the even what a Canon will
see. Or are you trying to repro using a linear curve?
I suppose I have to state this again and again, it's when you need to
optimise a region of copy work with the el cheapo Canon DSLR then you may
find advantages in using multiple exposures in either multi layered files,
or HDR. Not so hard to figure out, unless you don't want to.
