Description of problem:
Since Fedora 23 is now EOL, fedora-review should no longer be complaining about missing gsettings-schema scriptlets. Fedora 24 and up do not require them, and the guidelines page about them says not to use them: http://fedoraproject.org/wiki/Packaging:ScriptletSnippets#GSettings_Schema
Version-Release number of selected component (if applicable):
I can confirm this issue. I'm getting same warnings from fedora-review (same version, also Fedora 25) when inspecting some GNOME Shell extensions I'm working on packaging.
Still an issue in fedora-review version 0.6.1 f03e4e7 2016-05-02 14:21:43 +0200, running on Fedora 26 Workstation x86_64.
This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.
Marking as Rawhide, Triaged, and FutureFeature so it doesn't get accidentally closed.
