I ran into this while attempting to debug a test failure and was wondering why py36 was passing yet py35 and py37 failed.

We should probably be using https://tox.readthedocs.io/en/latest/example/basic.html#compressing-dependency-matrix to avoid these kinds of omissions.

I think the improvement comments should really be on #7949 since that is a much more substantive clean-up change.

The environment is defined but has no command. I added a default failing command in #9593 .

Thanks, @lukecwik. I incorrectly used Affects Version label instead of Fix Version for BEAM-8093, and it fell off my radar.
