I wanted to take a look at some of these bug fixes, and one of the linked ones [1] seems more like a feature to me. So maybe it should be the week of "low priority" issues, or something like that.

I don't mean to sound negative, I think it's a great idea. I do something like this at home from time to time. Just spend a day repairing and fixing things. Everything that has accumulated.

To be fair, the blog post does not explicitly say anywhere that the week was for bug fixes only.
