It is not about "priorities". Putting work into writing bug is utterly useless, because if the maintainer does not fix it in 2 months, the bug will be closed as stale. I am actually fine with open source project maintainer to prioritize stuff and hey, maybe that bug will be fixed in 6 months when they have time. But I am not fine being told "we did not had time for 2 moths, therefore we are closing your bug" as is standard on github now.

Do not throw the ball back with "this happens because bugs are not well written". Stalebot closes bug regardless of whether they are well written and ensures no one will put effort into writing another well written bug again.
