Thank you for your patience! 🙏🏼
It‘s been a while since I had free time to focus more on Nord, and my open source projects in general, and invest time in this issue due to work-life balance. Please keep in mind that maintainers must maintain (pun intended 😁) balance for their open source work and life to avoid burnouts so this gap in time has nothing to do with you or your contribution.

I recently published the first “Northern Post — The state and roadmap of Nord“ announcement which includes all details about the plans and future of the Nord project, including the goal of catching up with the backlog. This issue is part of the backlog and therefore I want to triage and process it to get one step closer to a “clean state“. Read the announcement about reaching the “clean“ contribution triage state in Nord‘s discussions for more details about the goal.

Therefore it has been added to the queue in the central and single-source-of-truth project board that is also described in more detail in the roadmap announcement.
