Please make Travis CI job optional on Python. The issue #376 prevents to merge PRs even when the Travis CI run succesfully.

For example, python/cpython#22513 was created 5 days ago. The PR lists two Travis CI builds. One is "Queued — Build Created", the other one is "Successful in 16m — Build Passed". Problem: if you click on the two builds... it's the same build: https://travis-ci.com/github/python/cpython/builds/188824091

Travis CI integration in GitHub is sick for several months and I'm tired of trying to fix it. Again, see #376 for the 3rd issue in 6 months.
