I would question why you would ever need to top the brake system up.
There should be no leakage of any sort, I for one would blanch at
driving any car that needed occasional brake fluid (I remember my 1970
Toyota HiLux Pickup and its regular master cylinder failures all too
well). Typically opened brake fluid is kept around for long periods of
time and mixed with new brake fluid, degrading the value of new fluid...
True that brake fluid in a tightly sealed can may be better than that in
the system, but it is not nearly as good as that from a new sealed can.
Moisture is death to brake systems.

This is something I question a bit.
If I have an empty system and a full bottle, then open
the bottle and fill the system, the two "systems" would
start acucmulating water at the same time.
Since the bottle seals and the system as a breather, I
would surmise that the bottle would actually do slightly better
at keeping the water out.
If nothing else, topping up the system with the fluid
from the bottle should not INCREASE the percent water
content.
If month old fluid on the shelf is garbage, I am not sure
how that prevents month old fluid in the SYSTEM from being
garbage as well.
