Sort of a recurring theme, I find. They have 600+ issues that have been open for over a year, was hoping they'd drive down the backlog a bit before declaring victory
Go look at any large project, they have 500+/1000+ issues and many are ancient. Chrome, Firefox, you name it. I wouldn't be surprised if many issues have even been solved or need new reproduction steps but there's a difficulty to triaging all the issues as well.
