Here's the thing: What attacks exist to recover data over-written just once
with a bunch of 0 bits?

No company (AFAIK) will recover data overwritten like that.

So now the attack model has to assume exotic alien tech. In which case
there's no way of knowing if eight or a gajillion overwrites of random bits
is enough.

It'd be really cool to see results for an attack that recovers overwritten
data. And what kind of data would be the most important.
