Yes. Sorry, my point is, all waterproofs will wet out if they're not reproofed at some point in time. E.g. none of them will bead water forever. Gore-Tex say:
If water repellency can no longer be reactivated by washing and drying you’ll need to reapply a durable water repellent (DWR). Be sure to always follow the manufacturer’s instructions for reapplication—and don’t forget to active it by following our instructions for tumble dry or ironing.
I'm sure there's some new fabric that will, however, stay waterproof forever without needing to be reproofed. In fact, there is. Gore-Tex Shakedry.
