  does your plan include having a version of the dpkg-shlibdeps that
works in "warning-mode" only so that we can have a more extensive idea
of how the things are going to be, before it stops the development of
the biggest and already hardest packages to maintain out there ?

  I mean warning that a new dpkg-shlibdeps is in town is a thing, but
having clues _before_ the storm on how bad the storm will be would be of
help. It's too early to break _everything_ in Debian. Please consider
that plan.
