 This is the middle ground between the two extremes. Ignoring a warning means
 finding it later in a log, if at all; breaking on one, with an
 [exception breakpoint](./breakpoints.md#exception-breakpoints) on `Warning`, stops
 you dead every time it fires. A notification just tells you, in order, alongside
 everything else the request did.
