What you don't get is profile independence, so if you loose the
definition of the pixels, you loose the workflow. Nor gamut
independence, since in converting into an RGB working space for long
term archiving and repurposing, the film gamut is cropped to that RGB
working space, and that is not the case if it stays in Lab where you
can take it to hifi color losslessly, come the day that we have file
format support for + 4 color workflows (and can compare film gamuts
and hifi press gamuts in 3D in the up and coming Seattle-based Disney
Studios of gamut comparisons -:)).
LAB is not lossless - needing more bits than most RGB spaces to get
the same accuracy.
Also, ICC LAB is not infinite, and many RGB working spaces include
colors ouside of ICC LAB.
There are many reasons (which we've covered before) why LAB is not a
good working space.
