For whatever reason, if the rebar rusts, small particles will flake off sooner or later.

Now, they will lay in the bottom of the tube, which is no big deal. BUT, if they get disturbed for any reason while the air is going, there is the possibility of them getting pushed inside the airstones, which might not be a good thing.
