It looks like supporting Restify 8 won't require changes to the plugins because the breaking change from 7 to 8 was dropping support for Node 4.x and 6.x (https://github.com/restify/node-restify/blob/master/CHANGELOG.md).

However, we should still have post-install tests for Restify 8.

@DominicKramer does that means this PR can go ahead, or is there work needed before the PR goes ahead?

[DominicKramer]

Yes, the PR can land. It should not break customers.
