resolves #2083

---

Before submitting the PR make sure the following are checked:

• Feature branch is up-to-date with master (if not - rebase it).
• Squashed related commits together.
• Added tests.
• Updated documentation.
• Added an entry to the CHANGELOG.md if the new code introduces user-observable changes.
• The build (bundle exec rake) passes (be sure to run this locally, since it may produce updated documentation that you will need to commit).

If you have created a new cop:

• Added the new cop to config/default.yml.
• The cop is configured as Enabled: pending in config/default.yml.
• The cop is configured as Enabled: true in .rubocop.yml.
• The cop documents examples of good and bad code.
• The tests assert both that bad code is reported and that good code is not reported.
• Set VersionAdded: "<<next>>" in default/config.yml.

If you have modified an existing cop's configuration options:

• Set VersionChanged: "<<next>>" in config/default.yml.

All good, I support the change of marking the cop as unsafe for autocorrect.

It would probably be appropriate to document the safety concerns using @safety. e.g.,
https://github.com/rubocop/rubocop-rspec/blob/v3.6.0/lib/rubocop/cop/rspec/expect_change.rb#L13-L30

@koic @pirj @bquorning
Thank you for your review.
I've updated the document the safety concerns using @safety.
