Darktable 3.0 workflow

so my understanding is that we should not do any more processing in LAB mode – which means I should abandon my dear Tone curve in LAB mode. Is this correct?

I don’t think you should abandon LAB tone curve. Some modules work on RGB Channels like demosaicing or white balance.
For other modules like a tone curve LAB mode offers much more editing capabilities than RGB. Just check this comparison of LAB and RGB.

LAB Mode Vs RGB Mode: Photoshop CS6

You can reproduce that with the tone curves in darktable. Doing these ‘crazy’ curves in LAB A and B channel don’t mess up your image since they don’t affect the L channel.
RGB channels don’t have this flexibility.

Moreover LAB Color is intended to approximate human vision. Watch the latest video by Aurelien Pierre from 10:15
