I have been on boats where the owners had removed the valences. Really made the salons seem much larger. So I considered removing mine which came originally varnished. But the boat's salon lighting was mounted there, two 12v lights and two 120v. I would also have had to modify the curtain mounting system in some way. I decided it was too much trouble. Since then I have utilized the space behind the valences for a number of wire runs for radar, antennas and a depthsounder. Unobtrusive and lots easier than going up through the crowded wire runs to the flybridge. And, I suppose, it keeps the boat original.
