Transparency is a good idea, but profoundly difficult to build as an
ecosystem. I'm merely encouraging far more caution in thinking that "*
Transparency" is just flipping a few bits and magically an ecosystem
capable of achieving the desired properties and goals pops out :)

So this is a bit of an inconsistent reply. You insist there are many, but
then only elaborate on one. This makes it unreasonably difficult to
actually evaluate the claim or the goals. The "problem reporting" method
can be expressed in the intermediate, and all the problems are suddenly
If that's the example, great, we've solved something in 5 minutes that
could have spent 5 years of unnecessary overarchitecture. Otherwise, we
need a more concrete list.

Great. So don't use it, and host it on your website.
I've snipped the remainder of the replies, because the point was to
demonstrate the basic problem space to be evaluated for any example, but
that wasn't actually done for the one specific example given.
I don't think this is valuable. If anything, I think it's detrimental, in
that the proposal is a premature attempt to standardize something that's
not well-understood nor demonstrated to be an actual problem. Considering
how much work is left to tighten up the validation methods still, is the
view that such improvements are not a priority, or less of a priority than
