Yes, that's what the definition says.
Because it was not acceptable according to that definition to have a package 
KDECMakeStuff, which all tier1 packages would have depended on, the files 
KDEInstallDirs.cmake, KDECMakeSettings.cmake and KDECompilerSettings.cmake 
ended up in extra-cmake-modules.
IOW, those three files exist only for KF5, and no other reason. Without KF5, 
they wouldn't be in extra-cmake-modules (that's why they are in a separate 
directory).
IMO, in that sense, those three files are part of KF5, logically. They simply 
are not a separate package because it was not allowed (by the definition) to 
have an official tier0 package.
See, if tier1 does not depend on anything else KDE specific, remove those 
three files from e-c-m and see how it goes.
