Adding to this, I also suppose - how many of those people who raised issues are still using LC now? Probably not a huge amount. I suspect a lot of other people have also moved on.
Aside from the regular contributors 'over there', are there new users still signing up? If someone signed up at the height of LC-user-adoption (whenever that was), reported their issue, to not have it resolved... they probably went away and found something else. They might have even forgotten the fact that they raised the bug in the first place!
I suppose that's also why nobody is going to be rushing to fix any of those now.
