FYI I started a process of closing out stale bugs. For now I'm specifically looking at bugs targeted for wallaby-3 [1].
I just did a first pass and have removed 'wallaby-3' as target for anything with status 'Incomplete' and older than 365 days - in total 81 bugs (details there [2]). I will then also move onto 'New' 'Triaged' and 'In Progress' (older than 365 days).
If you see a comment like [3] on your bug and you disagree please re-set the status and milestone but also add a comment about why you disagree ('still a thing', 'ongoing _there_' etc).
