I wasn't saying that SET shouldn't be jumbled, just that it seems more
reasonable to track it only when track_utility is enabled, rather than doing
so even when that's disabled. Which I do think makes sense for executing a
prepared statement and calling a procedure, since they're really only utility
statements by accident.

I wasn't suggesting doing so at all.
