Well, the problem is that no one knows for sure which bugs are fixed and which
aren't.  To be certain, a human needs to review each bug.  A bot can only guess.

Note that the bugs in my reminders are already automatically prioritized by how
likely they are to still be valid, important, actionable.  So one simply needs
to start at the beginning of the list if they want to focus on those types of
bugs.  Isn't this helpful?

A huge number of valid open bugs are not being fixed, which is a fact.  We can
argue about what words to use to describe this situation, but it doesn't change
the situation itself.

What is your proposed solution?
