We do this. Because frankly, very often the bug has been reported by others and has been fixed, we just can't connect the dots in our ticketing system.

That's of course less than ideal, but given that a lot of tickets we get are often very poorly described it's hard. It's one aspect I have genuine hope AI can help us with.
