Sean, as someone who has tried to follow this for a while, I'm confused
by a third thing.
Doesn't the TC recommendation given additional weight by the RT that we
not migrate file paths until the dpkg bug has been fixed  make it
impossible for the pre-conditions for disappearing files to happen?

I'd like to make sure that the bug submitter has not identified
something new here.

I think that if you are going to ask for drastic action like you are
doing, a turse mention on a wiki page is not sufficient documentation.
Simon's mail got significant attention because he actually worked
through and documented the situation.
I and I believe several people who have looked at this situation believe
that the RT guidance will prevent the issue Simon raised from happening.

I suspect that if someone were to clearly document a different situation
that had not previously been considered, people would look at it.
I'd hope the TC would be open to considering newly documented technical
problems as an example.
But because the decision has been made, the bar for blocking things is a
lot higher at this point than turse descriptions on a wiki page.
