   Actually the coverage is not stable at all. Look at this example report https://codecov.io/gh/apache/incubator-mxnet/pull/17905/changes which is based on #17905. The PR adds one new operator, but 132 files have coverage changes with a reported line changes in a four digit space. 
   
   That example is not ideal, but I couldn't find a recent PR which had a successful CI run and was a NO-OP. Maybe just create a few empty PRs, make the CI runs succeed and then you will have a few clear reports which show you exactly which lines are not stable.
   
   Generally we can only consider the coverage report stable if that page reports 0 changes for runs which do not change anything. Otherwise, these numbers are misleading and will confuse the PR authors if we enable the publishing.
