For some reason the conversion of RGB -->Lab has been particularly singled out for criticism in this respect.
it's a bad workflow because what can be done with an rgb->lab-rgb conversion can be done *without* the conversion and with better results.
Yes it can be done in RGB, but with a lot more effort.
nope. it's less effort and with higher quality results in rgb since you don't need to make two lossy conversions. it's also quicker.PeterNnospam
Take a simple example stock photo and change the color in RGB, and then make the same color change in LAB.
that's meaningless. change the colour to what?
If you had any good faith you would not say that. I posted a link, that says just the opposite, that you didn't read.PeterNnospam
Or, simply increase color saturation n RGB and make the same change in LAB.
there is absolutely *no* need to go to lab to change saturation.

All yo do is sout questionable theory. Show some real life proof.
there's nothing questionable about it.
read something *other* than the crap marguilis spouts and learn something new for once.
