I'm adding polished covers to all the caps, and it would be much easier to add a cover to the clutch resevoir cap if that vent area at the top was eliminated.
What natural disaster can I expect by sealing the top?

It's vented because there is a volume change inside the reservior every time the clutch is used.
Hygroscopic - yes but so far, that has not been our issue. Long term it could be but regular changes will eliminate that issue.
Disaster - broken or cracked reservior or blowing the unclamped line off the bottom of the reservior or master cylinder.
