Stephen,
perhaps the reason that the tools are not used is that they are not
adequate for the task. but it certainly does not follow that "if
one doesn't use the tools, then one does not care very much".

If one cares
about knowing where the data originated, and that it has not been
altered, then one needs to make use of the tools provided to address
that concern. if one doesn't use the tools, then one does not care
very much, and the results may be surprising :-).
