I don't see any reason why it should preclude netball or wheelchair sports. Although wheelchair users may have problems getting onto the raised floor unless adequate access was provided. I just don't see the Allams paying somebody to lay and remove the floor for a couple of hours.
I didn't look this Saturday but I'm sure I've seen the floor stored outside the Airco, open to the elements, at previous matches.
Again, it's my ignorance, as I have no idea how it works, but I assumed it wouldn't sit flat enough or have the required spring for netball, but assumed trampolining only needed a firm support under the actual apparatus.
