That is not completely correct, if bash was not essential anymore it
would not be possible to use it in maintainer scripts. (Even a
pre-dependency is not strong enough for .config or .postrm)

I agree that making bash non-essential might simply not be worth it,
it is no mightily big package (Installed-Size: 872 on woody) and does
not have big dependencies. The potential for breakage OTOH in not
negligable. And isn't bash an important part of having GNU userland?
