Personally, I’m perfectly happy keeping it open. The PRs we get seem to have high value to noise and low workload. That said, if they want to make this change Exercism-wide, I wouldn’t want to buck the trend.
If you’re happy to keep reviewing PRs and it’s not getting in the way of you using your time to do things that you enjoy more on Exercism (or that you feel add higher value), I’m happy for you to keep doing it
But I appreciate you wanting to follow the “Exercism-way” a lot
