This going back and forth between versions of npm 😃

Wondering if latest versions of npm are dependable enough that we could get rid of the "forgiveness" we include for optional, since at the time it was primarily a difference of OS (Travis Linux).

If we did that, even unexpected changes in optional would be marked by check-local-changes.

https://npm.community/t/package-lock-json-keeps-changing-between-platforms-and-runs/1129/16 - I found the related topic, the last report is from January, so it's hard to say whether it's fixed. We can give it a try and see if it is still an issue as it obviously prevents us from catching other issues.
