OK, the reason probably was that a renamed dependency contained equal
named files, hence to not break dependencies either the new or the old
packages were required, but installing the new packages with different
names required to remove the old packages first. To work around such a
dependency cycle, the maintainers of the third party repository probably
should have used transitional packages.
