That is what GR predicts. However we know that GR is incomplete because it is incompatible with quantum field theory. I was trying to illustrate what can be relied upon to be true even if ultimately GR gets superseded by deeper theories: namely, we can rely on an event horizon forming at the schwartzchild radius whatever the ultimate fate of the in-falling matter may be (in an infinite future).
Furthermore, whereas you and I apparently know what a null surface is, I was trying to illustrate what infinite time dilation means without resorting to very specialist knowledge.
