We attempted it in a previous OKR last quarter: https://gitlab.com/groups/gitlab-com/marketing/corporate_mar.... That's why I mentioned it in the past tense. This article was not part of that old OKR, you can see the issues that brought it up.
And the "we" there refers more to my team - the author of the post is on my team. GitLab OKRs start at the company level, but every team has their own that roll up: https://about.gitlab.com/company/okrs/.
