Well I was coming at it from the other direction -- questioning whether it's
at all useful and if it's not whether there's any marginal downside even if
it's slight.
The axis on which I still see real room for improvement here is on the
description of the locks. It's awfully hard for a user to tell from the
deadlock message exactly what operation of the query was acquiring what lock
when it deadlocked.
I'm not sure how to improve that though. It's an inherent problem that
understanding deadlocks requires understanding a certain amount of internal
implementation details.
