obsolete-not-provided
First of all, while you can put anything in an Obsoletes tag, only package names (with/without a version-release range) will actually result in the specified package(s) getting replaced with another package (or multiple ones).
Further, anything declared as obsolete breaks existing dependencies on it. Unless there is a corresponding "Provides" for the obsolete thing.
Obsoletes: libqore5 < 0.8.12
If there's a "Requires: libqore5 …" anywhere, there would be a broken dependency, regardless of whether "libqore5" is a physical package %name, a virtual package name, or something else as a "Provides" tag.

Obsoletes: qore-module-api-0.18
Same here. This capability will be "gone", "hidden" from the depsolver, and anything that still depends on it will cause a broken dependency. The package that contains this Obsoletes tag does not implicitly "Provides" the obsolete thing.
