I am not aware of these posts you speak of, but unless they are talking about very 1st generation TMs I can say without a doubt , that only a small snake or lizard would fall through the gap, and there is no way that someopne could reach the door handle to unlock it unless they had stretchy arms and can move like Gumby.  Someone is feeding you a line, and unless this is joke post, there are a great many TM owners that will bear this out.  To say that the velcro gave way. or was pushed up was obviously posted by a person without a TM.  Take another look at the gap and judge for yourself....but to worry is not warranted.
