The conclusion I'd draw is this... If you're confident in your own ability - or that of the camera - to achieve correct white balance and exposure, and you're happy to accept the camera's JPEG output with (potentially) limited room for corrections and other processing after the fact (depending on the type of shot), JPEG can be perfectly adequate. But when things don't work quite as expected in camera, or if greater creative flexibility is required in post-processing, shooting raw is far preferable. Raw plus JPEG offers maximum versatility, but relinquishes the camera's performance advantages in shooting JPEG only...
I'd say this is a pretty fair summary, and I also agree that correcting WB problems on a JPEG is a real PITA.
However, I'd rephrase one part of your statement to read "... if greater creative flexibility is required in post-processing
and photographer has plenty of time and energy to both to learn good post-processing techniques and to apply them, shooting raw is
usually preferable".
And let's not forget that although JPEGs are, for lack of a better term, "brittle", they do have
some room for corrections. I don't know why people insist on comparing only OOC JPEGS with extensively tweaked RAWs. For myself, I find that if I can get a good exposure in camera (and yes, good WB is super important), I can get a better image by
slightly tweaking the OOC JPEG file than I can by post-processing from the RAW file, and it takes me very little time and effort to do that. Of course, I recognize that if I invested the time to learn better post-processing skills, that would probably change. And eventually I could even automate some of the process. But for now I'd rather be spending more time out there, looking for bugs or perfecting my technique in approaching skittish ones (I shoot mostly arthropod field macros), or even trying out different lighting techniques. Perfecting my post-processing chops is pretty far down my list of priorities. But maybe I'll get there eventually.
Some people see photographs as the timeless and priceless capturing of a moment for all of eternity. These people should probably shoot RAW. For me, a photograph is the result of the work of artisanship that I am capable of producing at a given moment. I am not too interested in re-processing any but maybe the very best shots I produce in a year, and even then, I don't think I would do that more than once. If my technique (in the field or in post) improves, I would rather apply that to produce new and better work than to go back and improve a shot from several years back...
