Drush alias required with custom Drush binary

[ataylorme]

Hi @jhedstrom,
In pantheon-systems/example-drops-8-composer we are attempting to use terminus as an alternate Drush binary when running Behat tests against a remote site.

terminus drush runs drush over SSH on the remote site directly. I don't think an alias should be required in this case. I see that drupal/drupal-driver has a v2 RC and drupal/drupal-extension has a v4 RC.

Is it worth troubleshooting this issue in the previous versions, which we are using, or should we try to implement the RC versions?

Turns out it doesn't matter.

Here is an example failed build on the stable version and an example failed build on the RC version
