Think of the null hypothesis. The null hypothesis is the hypothesis that a relationship between two (or more) phenomena does NOT exist. Using this sort of model for the burden of proof avoids contortionist rephrasing of claims so as to avoid having to defend one's position.
Also, ought implies can. Given that (except in special cases) non-existence can't be proven, it makes no sense to say that one ought to prove it. FWIW I'm aware that many weak atheists take your view of the burden of proof, but it seems nonsensical to me.
The null hypothesis is just that, a hypothesis, which isn't a criticism of its usefulness, it is just to say that if one makes the claim "the null hypothesis is true" one still has to defend that claim. For instance, I can claim that being the president of the US is unrelated to whether one is a US citizen and I would have a burden of proof to defend that claim (something I would fail to do) despite it being the null hypothesis.
You are correct to note the relation to this comment between weak and strong atheism. The A above is indeed (a common variant) of the weak atheists position. While it is possible to have "weak theists" who make the comment T, it is rare that this actually occurs, most (but not all) theists are strong theists in the sense that they assert "god exists" (sometimes qualified in various ways).
It is also false to say that "non-existence" cannot be proven. As a mathematician I prove that, say, elements with certain properties cannot exist all the time. I wouldn't say this is even an issue of "special cases", I submit that a priori there is nothing that makes nonexistence in some way fundamentally harder than existence. Although I acknowledge the validity of the general heuristic for questions in the domain we are talking abuot.
