baloo5.spec:
%{_kf5_includedir}/Baloo
-%{_kf5_includedir}/baloo_version.h
+%{_kf5_includedir}/Baloo/baloo_version.h
The line could be removed completely because the whole dir is listed anyway (in the line before).

Similar in kactivities5.spec, kbookmarks.spec, kcalendarcore.spec.

kdeclarative.changes:
It's not necessary now as "the Frameworks that actually require
This sentence is truncated. The full one is 'It's not necessary now as "the Frameworks that actually require Core5Compat have been changed to make their linking to it PUBLIC."', although that's not really very informative either, so maybe it's better to just remove it completely...

kdelibs4support.spec: maybe explicit "BuildRequires: cmake(KF5Auth)" should be added (see changes), though apparently not necessary.

kjs.changes:
Revert "Install kjs_version.h in /usr/include/KF5/KJS/"
This reverts a commit from the same version, so no need to list it. The original commit (that was reverted) is "GIT_SILENT", maybe that's the reason why the revert was not removed by the script?

solid.spec:
-# Copyright (c) 2022 SUSE LLC
+# Copyright (c) 2021 SUSE LLC
I guess that's unintended... ;-)
