Of course if it is a shared reservoir, you should do brakes and clutch together - just regard the CSC as a 5th brake caliper.

I fully agree but I doubt if the dealers do it - hence there is also a risk of corrosion in the clutch master or more likely the slave cylinder (brake fluid is hygroscopic, which is why replacement is recommended every 2 years).
