Looks like the wrong way to fix it. It is rpm which should be changed to call
7zr instead of 7za, so that p7zip-full isn't needed. Same holds for all other
packages with direct dependency. The whole point of splitting the extra
binaries to p7zip-full was that 99% of the users could live without it and get
a smaller base install. If 15 packages trigger the installation of p7zip-full
directly or indirectly, including the very popular ImageMagick, then the whole
effort is ruined :(
