Taking the thread title literally, "Can a Tobacco Chamber Be Too Wide and Shallow" the only logical answer is yes, because of the vagueness of the question. It can equally be stated without fear of disproof that a tobacco chamber can be too narrow and too deep.
But the chambers that are made by competent craftsmen large fall within practiced norms. So if someone can't manage a particular shape, it's not the fault of the shape. This is just another case of the carpenter blaming his tools.
Just because a pipe smoker can't manage to smoke a pot, something that literally millions of other pipe smokers have managed to do over a hundreds of years, isn't likely the fault of the pot, but the fault of that smoker. We have different preferences, but that's personal choice, not the fault of the gear.
