Brake bleeding done with 1 L of fluid

Why wait for a failure - the fluid is hygroscopic and so attracts moisture. While this is not a serious thing in a clutch hydraulic system, if neglected the moisture will attack and rust out the slave cylinder piston and sleeve as you say.....
Changing the fluid every 2 years will save the slave cylinder & you will get many years of reliable operation.

All absolutely true and good advice. Just didn't want people to think it was an essential part of a complete brake bleed. In my race car I completely change the fluid every second race, the clutch however, every year at best.
