Comment:

 Thanks for the patch, @CrazyJaco.

 I think this is a bit of a risky change. The idea behind the saved queries
 and the associated debugging data is that a debugging plugin can make
 assumptions about what data is present in the `wpdb::$queries` property.
 If a filter is added here, then that (somewhat weak) contract is broken.

 I wonder if it would be better to add an extra element to the stored query
 data, the value of which is a filterable array of "extra" and arbitrary
 information relating to the query. That way a debugging plugin can use an
 expose that information as it wishes, but without the need to worry about
 which data is present in the stored queries and in what order.
