I work with RGB docs, but I can’r create RGB swatches. When I try to create a new swatch in the Swatch Panel, I can select RGB or HSB mode to specify the color, but the new swatch is saved with a CMYK approximation.

I avoid CMYK like the plague. It’s been around for over a century, and it’s flat and dull compared to RGB with up to 12 ink colors delivered by modern printers..

Please enable Illustrator to create RGB swatches, as well as better RGB support in General.
