You also wouldn’t say that a surface that could be dried by wiping wasn’t wet if it had water on it, but claiming that any surface in contact with water is wet insofar as it is not water implies that.

Take a grain of sand from a heap. Is it still a heap of sand? Probably.
Take another grain, then another. Keep going until it’s no longer a heap. Could take a while, but you’ll get there eventually. When exactly?
When you do, you’ve learned how much these fuzzy definitions suck.
The most formal definitions of heap generally concur that the heap would persist until it were empty.
