Warn cloners if there is no LICENSE* or COPYING* file that makes the license clear. This is a useful warning, because if there is no license somewhere, then local copyright laws (which forbid many uses) and terms of service apply - and the cloner may not be expecting that. Many projects accidentally omit a license, so this is common enough to note.
You can disable this warning by setting "clone.skiplicensecheck" to "true".
