So your assertion is that you have seen it in writing, so we should
all assume the drives will adhere to that, but the writing is private
and can not be verified and the manufacturers can not be held to it if
they choose not to abide by it in the general case, but we should
assume that if they are bound by private contracts, that they would
perform the same way with publically sold models that claim to have
the same model and revision?

I'm not saying a hard hell no, but this certainly makes me
uncomfortable.  I'd much rather see the manufacturers put it in
writing that yes, this make and model will perform this way even
though it is not strictly required by ATA8.  What would be better
still is if the bloody ATA standard got a clue and said that if the
drive claims that it does in fact zero after TRIM, that the TRIM
command becomes mandatory instead of advisory.
