Re: Bug#1119962: graphicsmagick: Uncoordinated transition dropping graphicsmagick-imagemagick-compat and graphicsmagick-libmagick-dev-compat

build-rdeps is needed here but of course that will include alternative

How many explicitly b-d on graphicsmagick-imagemagick-compat vs how
many are there via the Provides I don't know. That's all stuff to do
You can get an idea of this by running the same commands that the
archive team would use to remove binary packages, in "dry-run" mode,
against the DD-accessible mirror of their database that is available on
coccia.debian.org:
----8<----
smcv@coccia ~ % dak rm -R -n -b graphicsmagick-imagemagick-compat graphicsmagick-libmagick-dev-compat
Will remove the following packages from unstable:
graphicsmagick-imagemagick-compat | 1.4+really1.3.45+hg17696-1 | all
graphicsmagick-libmagick-dev-compat | 1.4+really1.3.45+hg17696-1 | all

This suggests that at least those 6 source packages are going to need
fixing.
Unfortunately `dak rm` doesn't seem to take into account
Build-Depends-Arch or Build-Depends-Indep, if that's significant here
(#1118954).
I also tried this, producing a slightly longer list of source packages:
$ grep-dctrl -FBuild-Depends-Indep,Build-Depends-Arch,Build-Depends -sPackage -e '(^|,) *graphicsmagick-(imagemagick|libmagick-dev)-compat' /var/lib/apt/lists/*{sid,unstable,experimental}_*_source_Sources
Package: budgie-backgrounds
Package: isospec
Package: massxpert
Package: octave-queueing
Package: ponyprog
Package: postgis
Package: pyx3
Package: sdcc
Package: zipios++
which should find only the Build-Depends{,-Arch,-Indep} on these
packages that either have no alternative, or are the first one in an
alternatives group and therefore would be used on the sid buildds. (Note
that the experimental buildds do not have this restriction, and will
sometimes - not necessarily deterministically! - use a non-preferred
alternative.)
This list is similar to the one Santiago found by literally doing the
rebuilds and seeing what happened, but not identical: he also had a2ps,
latex-mk and moviepy (I think the reason these are not on my list is
that he fixed them in unstable already) but for whatever reason not
massxpert.
Other lists of (this time binary) packages that could be relevant for
this transition:
$ grep-dctrl -FDepends,Recommends,Pre-Depends -sPackage -e '(^|,) *graphicsmagick-(imagemagick|libmagick-dev)-compat' /var/lib/apt/lists/*{sid,unstable,experimental}_*_Packages|sort -u
Package: recoverjpeg
$ grep-dctrl -FDepends,Recommends,Pre-Depends -sPackage -e 'graphicsmagick-(imagemagick|libmagick-dev)-compat' /var/lib/apt/lists/*{sid,unstable,experimental}_*_Packages|sort -u
Package: auto-multiple-choice-common
Package: epix
Package: flydraw
Package: jhead
Package: latex2rtf
Package: megapixels
Package: recoverjpeg
Package: wesnoth-1.18-tools
Package: wims
